I guess some people don't like connotations of the word and assume it's only applicable to systemic distribution of "wrong" points of view.
When certain (randomly picked by me) set of accounts for a year talks about "gender something...", "man something else...", "2nd Amendment...", "new use of chat AI..." or just some memes and all together (perceived by me empirically) start to translate "Instead of sending help to Ukraine Biden should send help to deal with Hawaii/SF fentanyl.../South border...", I jump to conclusions. Without mentioning Ukraine all these problems are real and do require some form of government intervention. The moment Ukraine appears in the discourse it makes one wonder how shipping M142 HIMARS or MGM-140 ATACMS to Hawaii would help.
Its also not true. Elon is a liar when he claims that X is a free speech platform.
I'd expect, all else being equal, for Facebook to be the biggest source of disinformation by the nature of being like 10x bigger than Twitter/X.
