You all believe that Blizzard and Activision actually care about their appearance? HA!!!! A simple google search for Bobby Kotick's bonuses along side mass layoffs will show you they don't give a care about their appearance. What they do care about is MONEY.
Now I pose this theory to you. Mind you this is just me, but Its me thinking like Activsion-Blizzard, namely Bobby.
Oh cool, we got this expansion out and we wanna use Kael'thas again, also we're bringing back an older expansion with heavy Kael'thas voice lines in it and we will probably need to re-record most of them for better sound quality and such. Oh shit...we have a contract with this guy who at the time, was an up and coming voice actor, but now he's quite famous and his price is astronomical compared to back then... If we break the contract we can be sued to high heavens unless.... yes! YES!! The Morality Clause. If we cite the accusations brought against him... we can end his contract, remove his voice lines, and hire some new shmuck to record them for cheep! Oh...and I'll get to keep whatever extra money we were gonna pay him as a bonus... OH BOBBY YOU DONE IT AGAIN!!!!
That's my theory. Blizzard didn't fire him cause of Cancel Culture, or Me too, or anything of the sort. They fired him to save MONEY and used any excuse they could. Had Quinton not taken off cause of Metal Gear and other games, they would have defended him cause he would still be a cheep hire. However, because he is famous and worth a lot more, he got the boot.
