GPL does not permit additional conditions, it actually states that additional conditions may be removed by the licensee.

In this case, I don’t see the actual license containing additional conditions, simply that the FAQ guidance on the page is misleading.

But it needs attribution and he can say what attribution is valid, no? IANAL so can't say for sure but does GPLv3 have same issue as early CC? https://doctorow.medium.com/a-bug-in-early-creative-commons-...

Yes and no. While the author can specify an attribution notice, the GPL limits it to being relayed amongst “appropriate legal notices” - these typically appear in an EULA or About screen. Otherwise an “inappropriate” attribution requirement could be misused to prevent modification of certain parts of the work.

As for the issue with CC, GPLv3 gives a 30 day grace period for rectifying violations which obviates many potential troll issues.

Thank you.
