I’m afraid you may have some misapprehensions about how trademarks work, and I don’t think this is about trademark specifically anyway.

Trademarks do not give someone the exclusive rights to that word in all contexts. Instead, you register a word or phrase and an category. For instance, there are about 1500 trademarks on the word Apple, from laundromats to eyeglasses[0]

But Meta’s complaint here doesn’t seem to be trademark; companies don’t typically trademark every name like filters. But there is lots of other IP law, including trade dress, which is different from trademark.

And much as I love the fediverse and hope it displaces dinosaurs like Meta, I’m surprised anyone would defending taking the filter names em mass and using them to refer to the same visual effects. That is not something one does. Meta is not claiming ownership of all uses of those words in any context, they are saying please don’t rip off the exact words to clone their UX.
