I feel ya. To me, it’s really sad that some new projects now use licenses that are really good for businesses but do not even protect the projects themselves. I’d rather live in a world where GPL share would increase. (Instead, GPL grows, but its share is diminishing.) All my projects so far are GPL/AGPL.

At the same time, Rust being picked for Linux has really nothing to do with the license. It’s just what you said - a coincidence. The actual choice is made because of the language itself. It’s a great language BTW.
