The difference is that the R-word foundation goes above and beyond their (reasonable) interests of protecting their brand/identity. This is not about trying to fend off people impersonating as "Official Rust..." or "Rust Foundation ..." but tries to stop you from even having the _word_ "rust" or "cargo" in your domain name. Also there is some ideology-driven nonsense which is impossible to enforce but that does not stop them from the attempt to treat their community condescendingly like that.
