FCC blocks Tor so I can’t see the page, but I just wanted to mention a hack if number porting is refused for some reason (based on @[email protected]’s hint that it could be): downgrade the vz contract to the full extent possible (ideally make it a prepaid acct if that’s possible, so you can nix the monthly fee).

They are centralised in the walled garden of Cloudflare. Access to all those instances is dictated by a gatekeeping tech giant in the US who excludes several demographics of people. Lemmy World and some of the others are also centralised by disproportionate size, which is enabled by Cloudflare with no sense of self control on growth.
Ethical users who are informed about Cloudflare avoid those centralised instances. The purpose of the fedi is to balance power. Those instances represent an attack on that principle. In principle it’s not much different than doing a community search and getting half a screen full of Facebook, Instagram, and LinkedIn links.
