He could very well write a custom GPL that is compatible with regular GPL, thus allowing any project to include his project to be GPL or his custom GPL, not only his GPL variant.

[NotEMoose → TheDong]

Except the GPL is actually non-free:

However you could make a derivative, but it's of little value.

[belorn → NotEMoose]

The preamble text of the GPL is non-free, as is the usage of the name GPL and GNU in it.

I could not find if GPL and GNU is trademarked, as that would serve a similar purpose.

[nsgi → TheDong]

The project would have to allow commercial use, which would contradict his custom GPL.
