If we get Overwatch out of the equation, this is mostly right, the problem is that the case are so anecdotical that is hard to prove (if ever able) and i don't feels like counting who get screwed more than the others, i'm obviously biased since i have a skin in the fight and since Blizzard GM aren't one entity and comport many people, one might make a shortcut to think that the political leaning of Blizzard Entertainment might sway who get a position in it or not.
Which enter in correlation with the second point, private company's website, at which point a PCW stop becoming a PCW? does a lobby with top dollars can pass as a PCW and censor subject or people they don't like? i'm almost certain this question alone would fill a thread, but i don't think i'm competent enough in this domain to judge it.
I could be mean and point out that i could mention that it suit you since most of the TC are left leaning, but useless since you would answer that i would still be whining about my side.
I appreciate this conversation none the less.
