It's not that easy. My Blizzard account is over 10 years old - never thought they'd go down hill so much. What's the solution, to never create accounts online anywhere? Even if a service looks good and you support it, a corporation like Activision can come along and have their asshole CEO infect everything.
Walking away from my account now means throwing away a lot of money spent on it.
I'm not supporting them, I haven't bought anything from Blizzard since the last Protoss SC2 game ages ago. But I don't want to lose access to my games.
I played Vanilla WoW a week after launch and was with it all the way up through Cataclysm Mists. After hearing about the multiple shocking incidences of sexual harassment and gender discrimination at Blizzard and upper management's unwillingness to stop it, it was quite easy to delete my Battle.net account and walk away. (Yeah I hadn't played in a while, but I'd intended to come back eventually.)
There are plenty of other games out there. You vote with your dollars, and your vote shows your character.
I walked away from my account with the Hong Kong stuff after spending an uncomfortable amount on Overwatch. Every decision they've made since then has made writing it off easier. I still have my Starcraft and Brood War discs, I enjoyed my time with WoW, but I don't see a reality where I turn back to Blizzard without huge internal changes.
Don't use McDonalds or TB app anymore. Praying Dunkin don't pull this bs. Every few times I go to McDs and they ask I wanna respond, "no cause forced arbitration is dumb for just a hamburger"
