My response,
"Should a social media site attempt to stop people from using it as a hub to follow everything they're interested in?
"Is this a trick question?
"People use Twitter to keep up with creators. If they can't have this as their one-stop-shop for links to everything, they'll leave."
This proves that Musk does not understand social media or human beings. Blocking links to other sites makes your site less useful! People like Twitter because everyone is there, and they can get links to blog posts, and YouTube videos, and Instagram pics, and whatever, without having to jump around to a bunch of other sites to find out what's going on. The more content they have to go elsewhere to hear about, the less time they spend on Twitter, and the more likely they leave and never come back.
Talk about cutting off your nose to spite your face.
