Context:

Permissive licenses (commonly referred to as “cuck licenses”) like the MIT license allow others to modify your software and release it under an unfree license. Copyleft licenses (like the Gnu General Public License) mandate that all derivative works remain free.

Andrew Tanenbaum developed MINIX, a modular operating system kernel. Intel went ahead and used it to build Management Engine, arguably one of the most widespread and invasive pieces of malware in the world, without even as much as telling him. There’s nothing Tanenbaum could do, since the MIT license allows this.

Erik Andersen is one of the developers of Busybox, a minimal implementation of that’s suited for embedded systems. Many companies tried to steal his code and distribute it with their unfree products, but since it’s protected under the GPL, Busybox developers were able to sue them and gain some money in the process.

Interestingly enough, Tanenbaum doesn’t seem to mind what intel did. But there are some examples out there of people regretting releasing their work under a permissive license.

    Busybox is very much widely used though?

    And how is it false that the GPL makes software remain free? Read the free software definition, it’s about the freedom of users, not the freedom of people who aren’t users (that doesn’t really make sense). Free software isn’t “source code available to general public even if they aren’t users”.

      I think the confusion here is selling software vs distributing source code. Free software can be sold, as long as you provide the source code and don’t try to stop others from redistributing copies for free. The busybox GPL lawsuits were about companies that redistributed busybox (or software built on top of busybox) without providing the source code. Whether or not they charged money for it isn’t relevant.
