Drop in replacement with less license issues, reactionary types endlessly arguing the notion of freedom, code that just works, and lots of development activity.

Drop in replacement with less license issues, reactionary types endlessly arguing the notion of freedom, code that just works, and lots of development activity. What is there not to like for the likes of Red Hat, Ubuntu, Google, Amazon and others providing Linux based products. In all seriousness, if you remove all non GPL licensed software from your Linux distribution because it's not pure enough, you'll be left with something that is a bit less comprehensive than your average operating system. It would miss things like a UI for example. Because both X Windows and Wayland are MIT licensed. A lot of popular server software that made Linux successful. And generally a lot of stuff that most of the OSS community uses and depend on every day. Like OpenSSH which is BSD licensed. Or things like Apache httpd (for which the Apache license was invented), etc. The GPL vision where all that stuff was going to be GPL licensed just never played out that way. Developers and companies decided otherwise. And this is fine. It's is not a problem that a lot of people believe needs fixing (as evidenced by a lot of non GPL OSS without good GPL alternatives). But of course if you feel otherwise, best of luck fixing that problem. The world runs on software. A lot of that is free and open source. And most of that is not licensed under the GPL.
