I really wish people would stop whining in the comment sections every time they see an article about Elon Musk and take some initiative to solve their own problems. Open uBlock Origin and add a damn filter. Adjust to your home instance:
div.post-listing is the element to block
:has(args) returns elements where args evaluate to true
span is the element with the title text
:has-text(needle) returns the element if it has the next needle, supports regex with \needle\ and remove case sensitivity with i
Edit: lol of course this was instantly downvoted. Because these kinds of people don't actually want Elon Musk out of their feeds, they just want to complain.
As much as we all hate hearing about Musk, he's a very influential person. The decisions he makes and what happens on Xitter can steer the direction of humanity, for better or worse.
Though let's be honest, this is not one of the influential/important things regarding Musk that should be reported on. It's just some idiots online claiming they'd do something they can't do, in order to make Musk-senpai notice them; it's not even about Musk per se.
This is good practice for you to just ignore the things you don't like. There is no such thing as safe spaces and you kids need to grow a thicker skin to survive.
