A little bit of context (https://en.m.wikipedia.org/wiki/Blitzchung_controversy)
In 2019, competitive Hearthstone player Blitzchung was removed from a tournament and banned from future tournaments for displaying a sign saying "Liberate Hong Kong, revolution of our times" in accordance with Blizzard's policy against political protest during events
Now that they've Targeted Gamers, there was a massive outrage, and the hearthstone community got pissed, so they protested in the following ways:
-Pretending to delete their account
-Preparing for some big protest at Blizzcon
-Some weird scheme to associate Overwatch's Chinese character Mei with Hong Kong protests, in hopes of getting Overwatch censored in China (obviously didn't do anything, based on the myth that Winnie the Pooh is banned in China)
-And most importantly, making big posts about how mad they are
Eventually, Blizzcon rolled around, no protest materialized, and they announced Overwatch 2, so everyone let this die, everyone let Hong Kong be forgotten. A stunning example of Reddit activism, I'll never forget it
IIRC the points of the protests were:
From talking to people who immigrated from HK and still have family there, the protesters generally wanted some good things, the problem was that the US will use any opening it can as a wedge issue. About half didn't support the protesters because "they caused too much property damage" or fought back against the cops.
In terms of actual results, there was an election and a "pro-democracy" group won in a landslide... except for all the seats that are appointed by corps. I don't think any of the demands were actually achieved but I'll admit that I haven't been paying attention. In the early days of COVID, HK police shut down any large gatherings, and I think the movement just kind of died from there.
