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.
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.
