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.
I’m not completely sure about this.
Suppose you write a library that a company like Facebook finds useful. Suppose that they incorporate it into their website. I’m sure I can skip the portion of this post where I extol the harms that Facebook has wrought on society. Do you think your software has improved people’s lives by enabling Facebook to do those sorts of things? They would not have been able to do them if you had used AGPL instead.
And I don’t want to make it seem like we should never do anything because someone might use the product of our work in a sinister way (because that would quickly devolve into nihilism). If 99 people use it for good and 1 for evil, that’s still a heavy net positive. But at the same time, I would be lying if I didn’t acknowledge that the 1 person using it for evil still would make me feel bad.
