The 'please ask' sentence could be read as implying that the authors
regard commercial and 'AppStore' distribution as not being allowed by
the nominal GPLv3 license. In the past I believe we've treated that
sort of thing as reason enough not to allow inclusion in Fedora. You
could try getting the upstream project to revise the sentence.
The author reply:
"Sure, I can clarify. It wasn't my intention to add exceptions to GPL.
As far as I understand App Store EULA is incompatible with GPL, so I
wanted to highlight that. How about:
For Free/Libre Open Source Software it's available under [GPL v3 or
later]
For use in non-GPL software (e.g. closed-source software or App Store
distribution) please ask for a commercial license. "
Looks good ?
