Yeah, I heard it was about the filter names, but previously had no idea what those filter names actually were. If they're common, obvious names like "blur" and "enhance", then I doubt Instagram would have a case, but if they're really the same as Instagram's, and Instagram's filters are indeed those on https://picturepan2.github.io/instagram.css/ https://picturepan2.github.io/instagram.css/ , and those names originated with Instagram, then Pixelfed needs to come up with some good names of their own, and fast. I'm a big fan of all the open source Fediverse platforms, but copying these sort of unique names is rather obviously a bad idea.
