Ah, yes... because Blizzard's image is pristine right now for their knee-jerk reaction and total silence for almost a week. It's pretty easy to draw a line. One person standing up to obvious, visible oppression is not a slippery slope. And even if it was, you know what's a good way to stop that from happening again? A warning. Saying that politics need to stay out of the interviews next time. That way Blizzard would have shown that they will not accept that kind of behavior, but they also wouldn't have been trying to silence anyone. Their bullshit message wouldn't be an obvious lie.
Instead, they decided to make an example out of someone and sided against human rights in the process, like a bunch of cowards.
