GPL would have helped with the concerns around the distributed software (instead of just source) not clearly including attribution/copies of the license (which would also lead to a better form of notification than the conference and webpage acknowledgement). These were also the types of points Tanenbaum famously regretted regarding MINIX https://www.cs.vu.nl/~ast/intel/ despite him not having the further regrets in the article.

I do agree for the author to be _fully_ happy they would probably have wanted something even more restrictive than any traditionally "open" license like GPL, but about any choice would have better aligned with their desires than MIT.
