There's a difference between disagreeing with a company and being saddled to one that's openly supporting the oppression of its citizens and murdering proponents of democracy.
I feel like too many here have forgotten the tragedies I've had the misfortune of living to see performed by China on the citizens of Hong Kong. And I don't want anyone to forget.
"There are no good companies", sure, but that doesn't absolve them of criticism, nor the employees AND consumers that know what is happening and remain silent. Again, there are many at Blizzard who have (and continue to) speak out. I'm proud of them and I support them. I hope taking their stance doesn't threaten their job.
But the very THEMES of Overwatch ("stand together!"), it's very creative goals ("bring the world together!"), it's very ambitions ("LGBT+ representation!") is at odds with the company that is making it right now and that is very much a conversation to be had. Yes, here, and yes, now.
It's topical. And it's IMPORTANT. One of the main characters of Overwatch is being used as a rallying cry and is being used by Hong Kong protesters at this very moment.
