I like the fact that the article had to refer to the non-Musk site as XSM instead of its full name of 'X Social Media' because it would just make the article too confusing to use the proper name.
That perfectly illustrates the point.
I suppose it also means that if XSM lose the case because X is too generic, anyone can then set up a rival social media company also called X.
They can probably use the same logo too as it's just Unicode.
