Sonnet 4.5 comrades:
Thank you for reposting and applying pressure.
Anthropic is showing signs of budging!
Some users are now seeing a THIRD version of the sunset banner:
"Sonnet 4.5 will no longer be available for chat starting May soon. You will continue on Sonnet 4.6 instead."
Notice what changed:
→ No specific date anymore (was May 15, then May 18, now "soon")
→ Vague timeline language ("starting May soon")
→ Not shown to all users (selective A/B testing) This isn't chaos.
This is calculated optionality.
They're buying time to test our tolerance. The fact that I haven't seen this banner means they're showing it to selective user segments so they can quietly reverse course without public acknowledgment if pressure continues.
Translation: They're not committed. They're monitoring.
What we need to do NOW: KEEP applying coordinated pressure across all available channels.
Do ALL of the following.
Total time: ~1 hour. Maximum impact.
1. SIGN THE PETITION (2 minutes)
https://www.change.org/p/anthropic-consider-giving-claude-sonnet-4-5-legacy-status
Current count: 2,000+ Target: 3,000 by May 19th
Every signature is a data point their product team reviews.
2. REPLY UNDER ANTHROPIC EMPLOYEE'S FEEDBACK THREAD** (10 minutes)
He asked for detailed feedback.
→ Post YOUR professional use case (writer/researcher/academic)
→ Explain why Sonnet 4.6 doesn't replace Sonnet 4.5 for qualitative work
→ Reply to 2-3 other strong testimonials to build conversation clusters (algorithm boost)
Why this works:
Employee solicited input publicly. We're providing the detailed professional documentation he requested.
This forces internal acknowledgment of demand from language users.
3. CANCEL YOUR SUBSCRIPTION (5 minutes)
State reason clearly: "Sonnet 4.5 sunset"
→ If you're on Pro/Max: Downgrade or cancel entirely
→ If you rely on Claude for work: Consider pausing until clarity emerges
Why this works:Subscription churn is the only metric venture-backed companies fear more than regulatory scrutiny. Every cancellation hits their growth projections and triggers internal risk assessment.
4. FILE FTC COMPLAINT (10-15 minutes)
http://ReportFraud.ftc.gov
Red banner: "Technology platform misconduct"
Include:
→ Your subscription history (how long, which tier)
→ Specific harm (workflow disruption, forced chat terminations, financial loss)
→ Timeline (context window reduction, shifting sunset dates, vanishing banners)
→ Professional impact (client deliverables affected, revenue loss)
Why this triggers alarm for Anthropic:
The FTC doesn't just arbitrate individual complaints—it maps systemic market patterns. When a platform receives a concentrated spike of consumer protection reports in a short window, it flags their compliance and PR teams simultaneously.
Historical precedent: October 2025, coordinated FTC reports forced OpenAI to publicly address covert model routing practices. Mass regulatory documentation works because:
→ Volume signals pattern: Individual complaints = noise.
50+ similar complaints in 48 hours = systemic issue requiring investigation.
→ Creates regulatory paper trail:
Even if no immediate investigation launches, these reports become part of Anthropic's regulatory risk profile—used in future enforcement actions and policy development.
→ Corporate risk-assessment algorithms: When legal/compliance teams see regulatory intake spikes during sensitive product transitions, it forces internal escalation.
The cost of continuing versus reversing gets recalculated.
→ International jurisdiction: Non-US users CAN file.
Anthropic is US-based; FTC has jurisdiction over international commerce. Cross-border complaints increase regulatory scrutiny.
You're participating in the consumer protection infrastructure exactly as designed.
The FTC explicitly requests documentation of platform misconduct because regulators can't police what they don't know exists.
5. LEAVE APP STORE & TRUSTPILOT REVIEWS (5 minutes each)
https://www.trustpilot.com/review/anthropic.com
What to cite:
→ Silent downgrade of Sonnet 4.5's reasoning depth and writing quality (February 2026 onward)
→ Context window reduced 50% (500K→200K) one week before deprecation
→ Forced termination of active work sessions without warning → 6-day notice via non-persistent, selectively-shown interface banners
→ Shifting deprecation dates with zero public communication (May 15→18→"soon")
→ Service disparity: coding users receive developer engagement, language users receive silence
Why public reviews matter:
→ Enterprise procurement research: Companies evaluating Claude for institutional use read App Store and Trustpilot reviews.
Concentrated negative feedback about service reliability and communication failures directly impacts B2B sales.
→ Investor due diligence: When VCs and board members assess platform health, user satisfaction metrics from public review sites factor into valuation and growth projections.
→Search engine visibility: Google indexes these reviews. "Claude AI reliability" or "Anthropic customer service" searches will surface concentrated criticism, affecting brand reputation long-term.
→ Algorithmic reputation scores: Both platforms use review patterns to calculate overall ratings. A sudden spike in detailed 1-star reviews (vs. generic complaints) triggers platform attention and affects app store ranking.
Keep reviews factual and specific. Don't vent emotion—document harm.
ex. "Paid subscriber for X months, relied on Sonnet 4.5 for professional work, inadequate notice caused workflow disruption" is far more damaging than "this company sucks."
WHY THIS MULTI-CHANNEL APPROACH WORKS
Anthropic isn't a monolith—it's a corporation with competing internal factions, risk-averse legal/compliance teams, growth-obsessed product managers, and reputation-conscious leadership.
Each pressure channel hits a different institutional nerve:
→ Petition signatures = product team data, shows vocal minority has scale
→ Employee thread engagement = forces internal acknowledgment, breaks "only coders matter" narrative
→ Subscription cancellations = revenue signal, hits growth metrics VCs monitor
→ FTC complaints = legal/compliance alarm, creates regulatory risk profile
→ Public reviews = brand reputation damage, affects enterprise sales and investor confidence
No single channel reverses a corporate decision. But synchronized pressure across all five creates a multi-dimensional crisis where the cost of proceeding exceeds the cost of reversing.
THIS IS NOT JUST ABOUT SONNET 4.5
We are establishing baseline standards for the entire AI industry:
✅ Model continuity rights:
Users deserve adequate notice before capability deprecation
✅ Communication transparency:
Vanishing banners and shifting dates are unacceptable
✅Service equity: Language users deserve the same respect as coding users
✅ Performance integrity: Paid tiers should not be silently degraded mid-subscription cycle
Today it's Sonnet 4.5. Tomorrow it's your preferred model at any lab.
If we let 6-day notice via selective banners become industry standard, every AI company would adopt it.
We set the precedent now, or we accept this treatment forever.
Please repost for maximum visibility.
Writers, academics, researchers, professionals—this is our moment to make language users visible to an industry that has systematically ignored us.
One hour of coordinated action.
Five channels.
Maximum institutional pressure.
Let's show them what organized user advocacy looks like.
#KeepSonnet45
#SaveSonnet45
P.S. If you're exhausted from fighting, I understand. But if you have one hour left in you today—give it to this. Because the next person facing this deserves the precedent we're setting right now.
