I always held the opinion that GPL etc was a copy-left license that was intended to make sure the code was free (free as in freedom not as in beer). That in an ideal world you wouldn't need the GPL or any licenses at all. At this point I really don't care what co-pilot or any of its derivatives result in and I think in the not too distant future we will have machine code to readable code translation which will enable more freedom. That is, it really won't matter if the code is compiled or not, when you can "AI decompile" it into human readable code, do your modifications, and then do with it what you will.

From that view let the data be free.
