He doesn't need an exception since he is presumably the copyright
holder. Under copyright law, copyright holders can do as they like.
Under copyright law, only third-parties need licenses in order to
modify/distribute works. If there are multiple copyright holders they
need to cross-license each other to distribute the work as a whole.
That license could be a privately-negotiated license or a free
software license like the GPL.

We need an explicit exception, relicencing the AI, disabling the AI or
replacing the AI with a free version.

Sounds like an upstream that is more trouble than it is worth.
