I believe a good chunk of western companies with subsidiaries in Russia will end up pulling out of Russia. The ability to move money in/out of the country makes it infeasible to do business (how do you pay employees if the funding is coming from the parent company? etc).
The Google situation seems a little different though as it looks like the Russian government forced their hand.
"People in Russia rely on our services to access quality information and we'll continue to keep free services such as Search, YouTube, Gmail, Maps, Android and Play available."
Maybe the assumption was that without revenue they would go away.
It was popular between Russian patriots to believe in a cunning plan of Putin. The phrase "хитрый план" (cunning plan) is a separate meme. But lately I believe they have no plans. They just do what they can, without thinking too much about consequences. And our Zombie-patriots never mention any cunning plans anymore, so it seems their beliefs in this regard are consistent with mine.
It is probably a propagandist action, like "see, we are fighting with evil Google and winning". There is no point to seek any deeper plans.
YouTube is a particular nail in the ass for Putin, because there are no reliable alternative in Russia. Rutube doesn't seem to be an alternative. They cannot just block YouTube. But they are talking about it a lot. So... "Lets do something, lets fine it at least, it would seem like we are fighting". It is like Cornelius Fudge imprisoning Hagrid not because Hagrid was guilty, but because Fudge needs to be seen actively doing something.
Any information on what resources Google actually had at risk / in play in Russia?
Given past hostility of the regime, my thinking is that other than current operating expenses (rent, salaries, cash on hand), there should have been little at risk.
None of the information I've seen has addressed these issues.
