The article isn't about being banned on Twitter. It's about automated moderation (a side effect of which is, yes, a Twitter ban.)
The title of the article is litteraly "How a Clip From Stray Got Me Banned From Twitter".
I fail to see why also discussing the reason of the ban takes anything away from my original point.
Because the thesis is that automoderation is a problem. The entire point of the article is using Twitter as an example of a problem, not the root problem itself.
