I don't think this compares directly to the now-commonplace kowtowing that you are referring to. That would be more akin to Zoom, for example, retracting and apologizing for some public statement that it made in recognition of the Tiananmen Square protests. Instead, this is a US-based communications platform, barring its US-based users from discussing something that is offensive to a foreign regime, and doing so outside of any official rules that they have made public. Now, of course, you are correct, this has nothing to do with any kind of deeply held values. It is merely about money. I don't think that makes it better.
