I don't agree at all. Your quote concludes with an attempt to completely sever ties with Oculus. I do not believe this was in any way a measured or reasonable reaction at the time. The nature of the underlying action is not changed by the fact that it happened to be phrased in a relatively respectful way in that particular post.
While technically true, that again makes it sound dramatic for no apparent reason. Choosing to not work with a company because you're uninterested in being associated with what they do is not something beyond the pale, even if many others have no problem with that thing.
To take a topical example, did Jonathan Blow "completely sever ties" with Microsoft because he has The Witness on PS4 and not the Xbox One because Sony actually cared about indie developers at the time he was looking at consoles to develop on? I guess you could say that if you wanted some click bait (and I'm sure more than a few gaming blogs did), but don't pretend that it's somehow getting to the "nature of the underlying action".
To me, this feels like an action that was intended to stir controversy, but I will admit I could be wrong. You may see it differently.
As for Jonathan Blow, I'll refrain from commenting because I don't know anything about that situation.
Not only did he address this ("I’m aware this goes against a lot of what I’ve said in public. I have no good response to that."), his public posts about it were fairly measured after his first response (which was mostly a few negative tweets):
> I have the greatest respect for the talented engineers and developers at Oculus. It’s been a long time since I met a more dedicated and talented group of people. I understand this is purely a business deal, and I’d like to congratulate both Facebook and the Oculus owners. But this is where we part ways.
It's silly to expect consistency in people's reactions to everything -- I doubt you are "fair" with every reaction you have to things that affect you -- but, regardless, "I still strongly believe that Notch (and many others) took it too far" is an (ironically) excessive reaction to what actually happened.
