An interesting response to Twitter's staged rollout of "you must be logged in to view tweets" surveillance misfeature ... would be for sites to ban Twitter links

I've been having that discussion with one popular tech discussion forum. They're considering the option.
On Reddit, such a block could be implemented individually by mods of key forums, as well as by Reddit admins themselves.
On the Fediverse and Diaspora, instance and pod admins can ban links to Twitter, or rewrite those to go through other interfaces (#Nitter and #Threadreader being the most viable presently).
And of course Facebook could do this, though given current Antitrust scrutiny, this might not be warmly embraced.
Note that the audience isn't merely Twitter, but those who rely on Twitter to spread messages and outreach. Given Twitter's relatively small direct userbase, the extended reach of links matters strongly. Breaking that reach kills Twitter's use value.
