Twitter is transforming into X, as the site’s former bird logo has now been replaced by an official new X logo. Elon Musk, who owns the transformed social media site, began signaling the change early Sunday morning with a series of tweets, starting with one that said, “and soon we shall bid adieu to the twitter brand and, gradually, all the birds.”
I think he means the artwork for the letter since the font is commercially available?
US copyright law doesn’t allow for protection of something like that. A dingbat, yes, but if it’s very plainly recognizable as an X then the exact shape and output of that typeface isn’t protectable. You can even print out a font, scan it, and create a new copycat font from it. The only thing you can’t do is reproduce the actual typeface file itself, which is fundamentally a single copyrighted piece of software. Some other countries allow more protection on the shapes of individual letters, but I don’t think you’d ever win a case anywhere on such a simple geometric shape as this X.
