How long has it been since Twitter became X and people and media STILL have to clarify that when they reference X they're talking about Twitter?

If I see the letter "x" by itself (not as part of a word) I assume either it means 'times' (multiplication) or it is a variable (which needs to be defined). Both of those things, of course, make no sense in the context of an article, title, and/or in speech therefore they have to say it means TWITter.
