To be clear for people that don't know: in October 2019 a Hearthstone (Blizzard game) player protested for Hong Kong while in a tournament stream, by putting on a mask (ironic right?) and shouting "Liberate Hong Kong".
Blizzard proceeded to ban the player, take away his prizemoney and also fire the live stream casters.
Following community criticism, they gave back the prizemoney to the player and reduced his ban to 6 months. Also, they said "the specific views expressed by blitzchung were NOT a factor in the decision we made". But in the official Blizzard Weibo account, they had mentioned they applied the ban to "protect China's national dignity".
Good videos about this:
