https://identi.ca/jxself/comment/ViGIl7lARfuc83wC6-qqkw reply to https://identi.ca/mlinksva/note/lizdsdoNSUe_6TXGyr4nRw notes that proprietary nullification would not kick in for a non-copyleft license, implying (if I understand correctly) that a permissive license could be offered in private, allowing incorporation into proprietary work, thus still circumventing copyleft through dual licensing.
The obvious way to close this loophole is to make the nullification kick in upon offer of any non-copyleft license of equivalent strength.
As the copyleft-next draft now has a network services clause, the only equivalent strength other license would be AGPL. Also changed derivative works section accordingly.
I've no idea whether this commit is the correct way to address the problem, if it is deemed a problem.
