Dear Anthropic, your broke our trust and I don’t think you’ll ever get it back.

My tokens will no longer fly your way.

Many users called Anthropic evil, scummy, and untrustworthy for breaking promises to builders and enforcing TOS against competing models while favoring big corporate clients.

@crazyox Its mostly because of the "we might be making the model dumber because we think you are working for competitors" which applies to basically anyone doing open source today. Open source from which they highly benefit, contributors like me who use claude on a daily basis....

Also noticing model getting worse, thinking naively "oh that generation is maybe not well trained" shifts now to "oh maybe they are nerfing us"

@art_zucker People considering investing in their IPO should consider this too. They’ll screw their customers they’ll screw their shareholders.

Something as consequential as AGI, merits a different treatment.

I wouldn’t index into temporarily unpleasant events. I was supposed to be damaged beyond repair from my time in grad school. Yet, I am here. I forgive people who “harmed and helped” me.

But people hold their emotions too high

@art_zucker The continued foot gunning catches up to them eventually. So stupid and unnecessary.

@art_zucker a lot of normies will continue connecting important data into claude via mcps and we will watch the disaster unfold in real time and no they will continue doing it
