The people critical of Putin and who are in Russia, and the people who don’t want to be a part of the war and who are in Russia would probably appreciate being able to more easily leave.
What do you mean when you say “vulnerable?” Is it just verbal flourish?
And those who haven't left, I'm sure there are ways they can be assisted too that we should also do. I'm not sure why "let's help this group" keeps getting interpreted as "let's punish this other group" :-/
Unfortunately these things are reportedly happening, the sentiment should be anti-Putin but ends up being anti-Russian, mostly thanks to Russians like these: https://t.me/glavredinfo/61841
If you don't mind me asking, why should the sentiment be anti-Putin? What makes you think that the war is not being supported by a significant fraction (if not majority) of the Russian population?
The point of my post was that it is not enough to help anti-Putin (and by that I mean anti-current-power-system-of-russia) leave Russia. They are as much victims here as Ukrainians who fled the war, but are sometimes treated badly.
Many of them are in countries that are happy to give Putin anyone he wants. A lot of political activists and detectors get deported back to prison.
