What "until"?
Blizzards artistic merit was killed by Activision, until you find out they have always had a female-abusive work environment.
What?
It's another valid reason to boycott blizz... But you're adding that factoid as if it counters mine? It's also not relevant for why their IPs are souring. It's another reason why they don't deserve customers, even if the games were still good, but its not the reason their games are suffering in terms of quality.
