Additionally all links to anything in mastodon (may be server specific) are also being blocked. Mastadon users are reporting this morning that they aren't able to post links to their Mastadon accounts with error messages that Twitter has identified the site as harmful.

Banning all links to Mastodon? That's just censoring the competition. Lots of people have been leaving Twitter for Mastodon, so silencing that might be a welcome side effect of widely overshooting his elonjet ban.

"Lots" might be an overstatement, in relativity at least.

The peak of the Mastodon migration was mid November, reportedly around 400k per week. This sounds like a lot, however a) many have moved back to Twitter due to it not being what they expected and b) Twitter has over 300m monthly active users.

It's still a lot. Mastodon has grown enormously. If Twitter keeps burning and Mastodon can handle the influx (the latter is the bigger 'if' here), that it may continue to grow.

It's entirely possible (although I personally think it unlikely).

Regardless, < 1% is not a lot of Twitter users by pretty much any stretch. I think people in tech or fringe communities are seeing a high uptake in their own groups and assuming that to be reflective of Twitter users at large.

Funnily this is what Freenode was doing for Libera mentions.
