nobody is going to stop you leaving the UK.

its entering another country that suddenly becomes a real problem, and ofcourse, if you're in the UK, the only country worth moving to at that point is the US with (as I understand) quite stringent immigration restrictions.

in reality, if the US were to open their doors to the UK, holy moly - this entire country would turn into Ukraine overnight, with nobody but pensioners left. which actually isn't in either governments interest: obviously not the UK, but infact, the UK presents a source of cheap labour for the US: read any hackernews thread concerning tech wages in the UK, the comments are hysterical/diabolical ("you make HOW much!?" - "A fast food worker makes more..." - etc.)

so, the current state of affairs is probably a good business arrangement for both parties involved, and aren't gonna change any time soon.

Not as many easy paths anymore for a British worker, tech or otherwise, thanks to The Foolishness.

And the most popular choice -- the USA -- is off the table for the majority of Brits, I think, who cannot comprehend The Other Foolishness. (Mind you, the ones it encourages... I hope they follow their hearts)

No need to leave, move up north and wait for all the shenanigans to blow over. Hard to be annoyed at the government and the corporations when you're walking through the Yorkshire dales on a sunny day
