That's because there shouldn't be one global boundary enforced centrally. This kind of problem is a direct consequence of the scale and alignment miss-match between the technical structures (here cloudfare) and the scale at which there is political cohesion (apparently much lower scale here, since there is such an irreconcilable disagreement). Each politically cohesive group should have the ability to make their own policies. That's how federated things work (email, mastodon or bgp). Hence these kind of clashes we get regularly because of the size of most things has become so huge which is completely nonsense imho (eurozone, food/simple goods production, media).
And frankly, the example of Mastodon doesn't inspire confidence. Mastodon instance-level blocks have turned the platform into a huge mess. I genuinely would not be surprised if there was no single instance I can sit on that will allow me to interact with everyone I know on Mastodon, and as far as I've heard, if I choose to host my own instance and not to block certain instances, this will lead to my instance being blocked on some instances. I could be exaggerating a little, but this seems quite annoying.
Admittedly, e-mail works a bit better in this regard, but it's certainly not without issues (SPAM, deliverability, etc.) Still, it's perhaps possible that platforms that deal with public broadcasting are inherently more sensitive to cultural clash than ones that only deal with more or less direct communication.
Consolidation of power into platforms like Cloudflare is still a problem, but even if we fix that, we still have another service that has a lot of people all in one big amorphous zone: the Internet. I do wonder a lot if the Internet will ultimately wind up unifying a bunch of cultures, or if it will wind up creating even more bifurcation than it eliminates. It's starting to feel more and more like it creates more bifurcation, just a bit.
This act is evil and morally wrong in all political reference frames. Anyone who’s arguing that it’s partisan or woke is focusing too hard on the victims, trans women, and not hard enough on the perpetrators.
Most people would say the legal system is the correct avenue for this.
My point isn't to weigh in on this specific decision, but I want the rhetoric around this stuff to evolve away from pretending that defining the boundaries of what speech should be protected is super easy and objective. It's really not, and it never will be.
