Earlier quoted context omitted.
Most Brits have no idea what's in the Online Safety Act since it expressly mandates the neutering of end-to-end encryption in messaging apps. And protesting is very difficult when everyone doing so is branded a child molester. Britain isn't a true democracy. Neither is Australia. They're Orwellian societies where the populace has been trained to believe that "the government knows best."
Brits want something roughly akin to the online safety act - they want liability for online unsafety. I doubt many of them care about the requirement for platforms to register or the fees for doing so, and would still support it if that wasn't in there. We should be trying to give people what they want in the best possible way. Otherwise, other people (with ulterior motives) will give it to them in the worst possible…
But the voices call for "robust" systems... And some parties are trying to implement that, and from there difficulties I mentioned in the other post.
