A set of licenses, based on the GPL, with additional clauses to prevent the use of the software for nefarious purposes.
EDIT: After some issues raised, I am rebasing the license on the Apache License 2.0 and taking more care in keeping it open.
EDIT 2: I’ve rebased it. I plan to submit it to OSI as soon as my law student friend has a look at it.
From the juridical point of view, citing the gpl in your license is terrible (you didn’t specify the version either). The best thing is to actually write everything from the gpl that you want.
Got it. First time I’ve written a license.
Although you have good intentions, writing your own license is probably not a good idea without adequate legal advice/background.
GPL and Artistic both needed a bunch of legal help to get them where they are.
Don’t roll your own cryptography and don’t do the same for software licenses.
Glad to be helpful.
