Disclaimer: I am not a lawyer, this is not legal advice.
The Fedora project has recently changed the classification of the CC0 license
to allowed-content
only, and will not accept CC0-licensed software going
forward.
This is due to paragraph 4(a) of the CC0:
No trademark or patent rights held by Affirmer are waived, abandoned, surrendered, licensed or otherwise affected by this document.
Such a clause may strengthen the case of a party that releases software under the CC0 that infringes a software patent that they hold, and attempts to sue those who use the software they release for patent infringement.
Software patents are deeply harmful to free and open-source software, and such a clause makes the CC0 less suitable for use with software.
In the interest of preserving the value of the CC0, I propose a minimally modified version with the following changes:
- Rename the license to
PD0
to avoid confusion - Remove all references to Creative Commons, since it is no longer a Creative Commons license
- Remove paragraph 4(a)
The modified license is in PD0. Each change of the above changes been made in a separate commit to this repository for ease of auditing.
