This is what the UK spyware proposal means.

There must be government spyware on every mobile device. It shall watch everything that happens, including always watching the screen, looking for things the government disapproves of.

When anything is flagged by the software as something the government doesn't like, the software must block it from being sent or displayed (in realtime).

The user of the device must not be able to shut this watching and blocking off. The only way to shut it off would be to ask the government or its proxies to do so for you, at their discretion.

Therefore the whole device must be locked down. Administrator rights and the decision of what software or operating system to run or not to run must be taken from the owner/user and handed to the government and its proxies.

Apple and Google are themselves working hard to lock down the devices they are involved in to shut out competition and establish a duopoly.

The UK government says it is "working closely" with Apple and Google and currently they synchronise and coordinate their communication on this subject.

The UK government is now proposing to mandate what would otherwise be illegal anti-competitive practices.
