Could you elaborate? What does this mean?

Edit: thanks for answers, this helps.

Yeah but I assume vast majority simply works from remote for the same companies they did?

Among them also Dan Abramov I think.

The talent has left but have you seen mass protests against Russian aggression in EU/US by those who left? I haven’t. And this is a big difference to the behaviour or Belarusians who fled - they are often seen across EU protesting against Lukashenko.

So the talent has left, but not because they disagree with Putin actions.
