It was just the weekly Internet drama of the programming niche probably pumped by Youtubers and influencers in need for content to drive views and then by memes. Barely anything of substance was actually written about it.
After all, if Matt were such a negative factor in the project, it would be trivial to just take all the code and fork it and then for all the developers to just move to the new project. The fact that this didn't happen shows that there is non-trivial infrastructure being provided that is separate from the open source project. How do such smart people as programmers fail to understand this when they repeatedly conflate the open source project with the whole trademark/plugin hosting thing is beyond me. Does nobody question the whole thing before pointing fingers and picking their pitchforks?
I've seen a Youtuber who interviewed to Matt in one video and the Youtuber himself raised the point of hosting costs, and then in a next video they conflate the two concepts as if they had completely forgotten about everything they said and heard. It's surreal.
