At first I assumed this was a joke of sorts.
Then I actually read the article.
It would appear this is one of the few times when the ludicrous amount of internet rage is not only warranted, but also nowhere near enough.
As mentioned before, Blizzard used to be a far superior company. Now Blizzard as we knew it no longer exists. Highly unfortunate.
Ah well, at least we still have Valve (though it's only a matter of time until Valve, one of the last non-possessed psykers out there, will succumb to the corruption of Chaos, and then we'll have to wait for other excellent game making companies to become sufficiently, but not too big while making excellent games and treating the customer base like a customer base, and not slaves - CD Projekt probably will become one of these, if they aren't already. But the more powerful a psyker becomes, the more daemons from the Warp it attracts, and sooner or later everyone will succumb, if they don't die(disband, in the context of reality) first).
This marks the start of the end for Blizzard, I would imagine. At least I bloody hope so, because this isn't the Blizzard we know from years back, this is the body of Blizzard, possessed by a daemon, and very little remains of the original - it's all mutated and broken now.
The only true solution here is an Exterminatus.
