That specific dev was completely banned from kernel development four years ago (two years later): https://lkml.org/lkml/2014/4/2/420. I don't know the persons involved and how much they contributed, but I'm wary of the implied cause.

I think it's related to this [1]. The tone of the conversation is unbelievable, is it normal to have this kind of flame wars on kernel?

Its not a like a workplace where the boss can just say "we're going this way". If two parties disagree then the standoff has to be broken somehow. Getting angry isn't always the most effective approach, but it does remove ambiguity about how much a person cares about the issue.
