(1) #Twitter has millions of users. There is no #ActivityPub nor #OStatus implementation in which an instance hosted on a $5/mo #DigitalOcean / #Linode / #Vultr #VPS could handle the volume of a seamless connection with #Twitter. If they adopted AP OStatus, #Diaspora, or any other current open federation protocol, instances that didn't use firewall blocking would topple once the two userbases had sufficient interconnections (within a few hours or a few days after they started federating).
(2) Twitter's business model is to push ads disguised as tweets. If their users could escape those and still interact with all the same contacts, they would. I'm certain that Twitter's management know this. They also turn all links into tracking links, and sell access to media (images, video, audio) uploads of important news events to news organizations.
(3) Most Fediverse instances are financed out of the admin's pocket. Some have financial contributors, but nothing like Twitter's revenue. As the largest and best-financed instance, they would immediately have to start implementing modifications to make AP or other existing federation protocols useful to them, and those modifications would (as Mastodon's currently do) become unofficially mandatory in order to be compatible.
(4) This isn't the first time that Twitter has considered federation, though this may be the first time they openly discussed it. Back when Identica was still a happening place (during Twitter's fail-whale days), Twitter considered federating. They didn't do it then, and I honestly do not believe they will do it now.
(5) I'd say that Twitter's #BlueSky initiative is more meant to try to get bidirectional connections across #Facebook's moat and wall than it is to surround Twitter with a cloud of #Fediverse instances.
They even built an entirely new feature around his account because the last thing they wanted is to suspend it for engagement reasons. The little panels indicating that his tweets were possibly misleading the public about an election https://twitter.com/joshscampbell/status/1324455120327725057 were just a workaround to keep his account online as long as possible.
Meanwhile, antifascist and women accounts have been suspended even without clear violation of the Twitter terms of service, just because an alt-right mob bogusly reported one of their tweet. So if Twitter wasn't coming for *you* before they banned Trump, they will not come for you next, you haven't been anywhere near Trump in terms of importance for Twitter's own business.
I'd argue that given their duopoly on mobile operating systems, the power to arbitrarily kick someone out is scary (regardless of how deserving Parler might be; I'm not even sure I've seen a screenshot of the site). I'd argue that this is evidence that the mobile OS and app store groups of both companies need to be split up, so that competition can come ... including strong competition for mobile app stores on each platform.
Again, Parler may deserve it, especially if their users used the socnet to organize their insurrection attempt. (Though I suspect many of them probably used odious #corpocentric sites like #Twitter or #Facebook, which are not being punished.)
@coolboymew @mangeurdenuage The weirdest thing is that #Twitter in the early days was a hotbed of real discussions, despite not having any real conversational features built in. Over time, a combination of too-rapid growth and their changes to the site made it so that conversation is painful (and prone to attract angry extremists who flock into one's mentions and immediately mark the person as part of $OTHER_GROUP.
And that's where many of #Mastodon's angry extremists learned how to coordinate and attack, so they can be really brutal to the unprepared.
Make sure every post you send has a link to your homepage or feed or Fediverse presence, so interested people can find your stuff when it breaks for good.
