Unfortunately this article isn't criticism, it's an instruction manual for groups that organize and co-ordinate using projection. Essentially anything groups aligned to authorities accuse outgroups of doing is a way of signalling and establishing consensus on what they plan to do next. They aren't projecting because they are stupid, they are projecting because they're coordinating. It only takes about 6-8 years to go from street riots to camps and gulags, and in Canada and Australia, we're about 60% of the way down that road. The only meaningful political question right now is how much civilization we must give up to isolate and remove a totalitarian movement that has subverted and taken root in our institutions, while they used other more legitimate movements as cover.
Complaining about censorship, or any signal of skepticism or belief in principle at all just gets you on a list of being among the first to stop applauding. Who really thinks someone who uses the cynical realpolitik of deception and censorship is going to be swayed by a principled argument?
The only thing nihilists understand is power and conseqeunces.
If you are really concerned about censorship, the most valuable act of defiance now is to build close personal networks of friends and family that do not depend on the platforms, and which are immune to the relentless official propaganda disgorged by tech companies.
This all sounds very dark, but really, if you can't countenance it, you aren't going to be innoculated to it, and you are going to be subject to it.
