Not much of a conspiracy. It's simply what's been going on behind the scenes from a political angle for a while.
I can't disclose much about this other than to say that the closure of these "comments" sections, which are akin to this forum's sections, was not a voluntary choice made by the publications who have chosen to do so. There has been building pressure for some time. MyBB has a slight issue with respect to moderating posts where the offending post in question has been amended by someone representing MyBB. This is part of what Paul was trying to warn MyBB about, and is why he lost his cool and targeted a few individuals with which to point out to MyBB the risk. It did however devolve into something completely different, as it does with this sort of thing.
I don't sanction nor agree with his methods, but I certainly understand what he was trying to do, and it was with the best of intentions...
