That's a fascinating take, but I don't think it's particularly related to what actually happened. I wasn't toxic because of some Microsoft FUD, I was toxic because I was a teenager with low empathy who hadn't learned things yet. I grew out of it.
Lots of people in open source were never particularly toxic, and there's no reason they should have been. Even granting the existence of the external stress (and it really was NOT that big a deal), not everyone reacts to stress by treating people badly. Furthermore, people who didn't grow up around those OSS advocates have exactly the same problems sometimes, for the same reason that people in every field of human endeavor have those problems sometimes.
