Indeed, the UK is almost becoming a police state. Your government spy on you at a rate that would make the NSA cringe and hardly anyone seems to care. There have been numerous cases like this over tweets and such.

Freedom of speech is the corner stone of a free society, allow them to start by curtailing it when you speak about things like this that many agree are taboo, and the rest are slow to speak out about in case their arguments are twisted to make it appear they are agreeing with the content rather than someones right to speak. That's the thin end of the wedge, soon it will be complaints about the the authorities. Then you wont be able to speak out about politicians, then its game over...

Oh and since they are monitoring all of your communications (and doing their best to backdoor, outlaw and byass encryption), perfectly lawfully in many cases because no one seems to really speak out about that either, it won't be just publicly shared videos, next it will be whats app groups then private messages to your friends...

Then they came for the Trade Unionists, and I did not speak out
Because I was not a Trade Unionist.
