What is the difference between:
- ISC License
- MIT License (Expat)
- BSD 2-Clause License (FreeBSD/Simplified)
The ISC seems to be a simplification of MIT and FreeBSD Simplified after Berne convention.
This license is functionally identical to the MIT/Expat and the Simplified BSD licenses, discarding some language that was made unnecessary by the Berne convention.
But I also see that ISC was patched since so it is good to use now:
Regarding the ISC terminology, Wikipedia states, 'Before accepting the license as a free software license, the Free Software Foundation (FSF) asked for clarification of the text. In July 2007, as a result, "and distribute" was changed to "and/or distribute".' So the license reads, "...modify, and/or distribute..."
I don't know if this wikipedia article is up to date and accurate but it seems to show that ISC is more vague about Patent grant, Private use, Sublicensing, TM grant.
