Software License

This is an interesting software license restriction on a software library called ExtJS…

ExtTLD is published under GPL 3.0 license however restricts use by companies participating in animal abuse, such as animal testing laboratories etc. For more information see our Terms of use.

The software has absolutely nothing to do with animal testing, but the project founder feels strongly about the subject and added the restrictions to exert whatever influence he can on animal abuse. Not a bad way to uphold your own morals.

    Well, yeah, except it makes it incompatible with every other piece of GPL-licensed software out there. Sure hope he didn’t copy and paste from anyone else’s software while writing it.

    It’s a web based library, but I see your point. I guess I needed a lawyer to point that out to me. 😉

    A GPL-expert lawyer, even 😉 There is a long essay somewhere about why, in the end, ‘extra’ restrictions like this are self-defeating, but I can’t find it at the moment…
