That's not what I hear from the people that I know on the other side of the divide. They know damn well why this is happening and who is in the driving seat but: they're scared, they don't want to be seen as unsupportive because people have already died because of that and they don't want to speak out because that's a surefire way of seeing your life completely screwed up or ended.
Putin is where he is because he doesn't hesitate to kill each and every person that questions his authority, you can't expect people in an environment like that to go out onto the streets to demand the dictators head because it will end in a very predictable way. But the general impression I get is that people are broadly visibly supportive but in private a lot less so if not outright against it. This makes it very hard to measure the temperature in Russia. There is a good reason why Putin keeps murdering the opposition (or removing them in other ways): he knows that if there is a fair election and a half decent challenger that he's history.
It depends on what part of the population, yeah young tech/internationally oriented people often yes. And also Russians in Europe often are anti-putin.
But Russia is big and I also know a handful of people where he is the one who gave stability & although they are not stupid the idea that he is fully lying or wrong is hard to accept for them.
They generally accept the Ukraine narrative the Russian Media portrays, since it's all they know; and they have no reason to trust the West more then mother Russia.
