GPL (and copyleft generally) gets way more attention than it should. In the wild, MIT and similar permissive licenses are by far the most common. Linux is on GPL, but that may be a historical artifact as much as anything. I don’t know if Linus himself would choose it if he were making the choice today. The wider FOSS community, in my experience, leans permissive rather than copyleft. The copyleft people are just loud.
