I think it seems just right. Languages these days are either controlled by volunteers or megacorps. Because linux is about freedom and is not aligned with megacorps, I think they'd prefer a volunteer-driven language like Rust or C++ rather than the corporate ones.
I’m not sure you can argue that Rust and C++ have anything like a similar story around being volunteer oriented, given the number of places that have C++ compiler groups that contribute papers / implementations.
Yeah I think if you want ideals and freedom you have to look elsewhere. It's not controlled by a single company, but it is controlled by a one digit number of them.
