Since nobody likes calling it X, why don't we call the platform "ex-twitter"? That way it's technically true, and everybody knows what you're talking about.
I mean, it still is Twitter. That's the URL that people use to access the site. Tbh I have no idea if Musk actually went through the effort of changing the company name in the business licensing or other company paperwork. Just the logo and header seem to say X. But I agree, I'm getting so annoyed with journalists calling it "the site formerly known as Twitter." so dumb.
