Oh "won't fight it" is an understatement: the british public are applauding this like a bunch of drooling trained seals. Once again, authoritarianism rises not via a bloody revolution but via popular consent. Oh yes, we'll keep kids from being able to see naughty videos, who could disagree with that? Oh sure, we'll allow people to get arrested for saying mean things online, it's hate speech after all.
Oh sure, we'll allow all encryption to be backdoored by the government, I've got nothing to hide! There's no way this could go badly, what are you talking about? It's not like there's a mountain of history indicating we're courting disaster.
Also let's not give my fellow Americans too much credit. A normie is a normie, worldwide. None of them realize they're being measured for their prison uniform until they're staring at the bars (and some, not even then!). We're going down the chute more slowly than you, and we're not as far down, but we're going, all the same. Half the US states now require porn ID, and the supreme court just reaffirmed this was totally fine and in no way a violation of privacy or the first amendment (which is bullshit, it's clearly an attempt at censorship through intimidation).
Also also, not to be grim, but I wouldn't worry about the phone stuff too much. Five eyes has been listening to pretty much everything for a very long time now. They don't care about the law, and never will. That was the whole point of Edward Snowden's revelations (which were summarily ignored by the general public).
