This is like the new "COD phosphorus" controversy of the week. A bunch of people are mad about something they didn't know they were mad about yesterday, nor did they give any thought about the controversy until it was time to be "woke up" by the media/social media and be mad/upset because its the right thing to do.
If you want to boycott ActiBlizzard because you are now all of sudden upset about the Chinese Government's policies/practices then throw away all of your clothes, cell phones, computers, gaming systems, office supplies, furniture, beauty products, pet supplies, etc. because you are the problem. By consuming all of those products your entire life you are supporting a communist regime.
Even if you boycotted Activision, you are still spending thousands of dollars a year supporting the Chinese Govt. by buying goods that they make, thus keeping their economy rolling.
If you want to be "for really real woke", then boycott everything you own and find products that China doesn't make.
