I often see Rust mentioned at the same time as MIT-type licenses.
Is it just a cultural thing that people who write Rust dislike Libre copyleft licenses? Or is it baked in to the language somehow?
Edit: It has been pointed out that I meant to say “copyleft”, not “libre”, so edited the title and body likewise.
You could say that, yes.
It makes sense to suggest MIT license for a MIT project
MIT is better than proprietary. MIT does not force you to not make your project free.
