What is your comprehensive alternate?
By cowing to oppressive government demands, rather than support the side of the spectrum they were born on, Facebook and YouTube allow the middle to move towards oppression.
In the same way that you do not reward a child’s tantrum with their desired outcome, you do not demonstrate to the world that they can have both YouTube and oppressive governments; unless, of course, you’re more interested in brief-but-immediate comfort than extended-but-delayed happiness.
Facebook and YouTube are happy to push their political views, so long as the consequences don't interfere too much with cash flow. As a secondary effect, they're happy to let you believe they're nonprofit-minded with profitable products -- and that's also good for business, as demonstrated in the negative by late-90s era Microsoft.
The same has been happening in the US and plenty of other non-Communist countries, over here we just prefer calling it "War against terror" or "You broke the ToS!".
