I like TinyMCE too and swapped out a Quill editor in its favor 6 months ago. But I was annoyed that you needed an API key to use their static JS in your site and disturbed that they rapidly shrunk free tier "use" of rendering an editor a few days back [0]. Out of curiosity, is that not an issue for you?
