There is some problem with that as you say, but the company doing the poll is pretty well-respected by the west. They were also labelled a foreign agent by Putin at some point, so I looked at their opinion.
There’s an estimate that <10% of people in Russia have motive to lie because of power they’d lose if their opinion got out, and the theory is that this is usually constant. Unless Putin is scarier than 2 years ago you can still compare differences in opinion, even if you don’t trust the magnitude. The guy also said that you can look at the positive responses as having a share of neutral because people who aren’t informed just go with the majority instead of saying “idk”.
But no matter how much lying in polls there is, the amount of people worried about sanctions went down compared to 2 years ago, and compared to 2015.
Which makes sense considering how much physical capital western companies left in Russia, since VW can’t take an auto factory back to Germany with them even if they can take some equipment (but not all).
They were right, they are an untrustworthy seller.
Reminds me of when all their customer data leaked, and obviously the people who pirated didn’t have that issue.
