This is begging the question, there's nothing confusing or incorrect about what GrapheneOS posted. GNU/FSF is a cult that has always been making their own arbitrary rules for what qualifies and what does not qualify as free software (I am not saying the OSI is any better in that regard, Raymond is a clown).

I highly suggest reading this mailing list thread where RMS fails to understand copyright law and thinks you can relicense permissive code to GPL, and refuses to call OpenBSD free because the ports system can be used to build a few pieces of non-free software, even though no parts of the ports tree itself are non-free (wait until he hears you can download Windows ISOs off of a web browser).
