Even if Blizzard games haven't had a high note since 2016, I would like to remind everyone that the company still had absurd amounts of goodwill and customer loyalty for a large and corporate studio at the time, with fans owning and actively collecting literal decades of merchendise.
Things only really truly collapsed for Blizzard and saw their goodwill vanish when they openly supported and endorsed the chinese oppression of Hong Kong.
Specifically, the winner of a Hearthstone tournament was interviewed after his win and gave the pro-Hong Kong slogan "free Hong Kong, the revolution of our times", which there was absolutely no rule or stipulation against. China demanded that the company not endorse that (because authoritarianism), but Blizzard ACTIVELY WENT THE EXTRA MILE to strip the player of his prize money and ban him from all future events alongside other punishments, specifically in the name of appeasing the chinese government.
It wouldn't be fair to expect a game company to singlehandedly stand up to an authoritarian regime that loves to make people disappear. But it is absolutely fair to recognize that Blizzard's actions very clearly demonstrated that they weren't just doing this because they were threatened into it- they were more than happy to actively endorse the chinese government's oppression of Hong Kong. And THAT is what we should always remember about Blizzard's morals and principles, or lack thereof.
