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.
Intel Management Engine improve no one’s life.
It is very sad how you don’t see that “forced openness” is good for everyone.
Yes, end products licensed as GPL are good. I use many of them. Libraries, however, are just avoided by companies and they just develop their own.
I prefer my libraries MIT licensed because then there’s a chance that people out there use it to develop products. If I make a GPL library then only products that were already GPL would use it. And there are way more proprietary products than GPL.
