The opposition to Rust is also strange. Yes, the trademark restriction is annoying, but it's not fatal: the existence of projects like Pale Moon and Waterfox show that forking projects in the presence of trademark restrictions is viable. (I still think Mozilla is really shitty for applying these restrictions in the first place though.)
Technically, Rust is a good thing. A way to structurally prevent memory safety defects is a major advance that occurs only rarely. Rust is the only game in town for memory safety if you also want low-level control over the machine. Giving that up over a trademark is just luddism.

I really hate how various corporate forces in the Linux world have made is socially unacceptable to sue people out of existence for blatant GPL violations.
