> Musk — who is no longer CEO of Twitter, but still deeply involved in operations — may also be motivated by a desire to prevent AI tools from searching Twitter.

This seems very unlikely. If they really just wanted to stop just AI tools from searching twitter, it would be very easy to prevent them from doing it at scale by imposing basic rate limiting and device intelligence (or even something like the puzzle LinkedIn makes you solve before viewing someone's profile while not logged in).

I'm very confused as to why they may not want unlogged-in human lurkers who are still seeing and clicking on ads when on the Twitter website.
