Just in case anyone else stumbles across this and is confused, I'll explain in more detail.
On Linux there are two display server protocols, the very old X11 and the newer Wayland, which was designed as a successor to X11 by its maintainers.
Elon Musk announced today that he is renaming Twitter to X (yes, just X). The above posts takes the mick out of this on this by announcing a social media website called Wayland, i.e. the successor to Musk's X.
To expand, one of his early businesses was X.com which was a payment processor and sold to paypal and eventually shutdown. He bought the domain again back in 2017 and it now redirects to twitter.
He’s also been wanting to name something X for a while. When Ford wouldn’t let him name the Model 3 the Model X (so his cars would spell SEX) he must have sat on his laurels until he had a brain aneurysm big enough to make him think it’s a good idea to dump the Twitter brand for a math problem.
Isn't it that he wanted model E but that's the one Ford wouldn't allow? Because there is a Tesla model X. He wanted to spell SEXY but instead he now has S3XY.
