I mean I guess I should have explicitly said "derived distribution for commercial projects" but I kinda thought that was obvious since nobody is going to use Genera as is, it would require substantial upgrading to make it useful for the 21st century. Which would be a derived work under GPL and require publication of sources if distributed etc. etc. GPL makes a lot of sense to me for something like this. Nobody is going to make money off Symbolic's old IP, but if they somehow were, clauses in the GPL3 or some variant of a copyleft license would likely force them to contribute back.
