That definitely includes people like me who thought signing up for GitHub Sponsors was a good idea. What's the worst that could happen, right? For all I know it could include projects that accept donations too. Is writing a book about the project or offering screencasts or whatever the same as offering "technical support services"? Is building a community on GitHub or Discord or whatever "providing a software platform through which the manufacturer monetises other services"? Who knows? I'm not a lawyer.
