So I just need to decompile Oracle's database and a few other commercial products as well and I'm good? Is Microsoft legal happy if I do Windows+Office+OpenSourceCorpus? I'd take that statement as well. Or even if they just do that themselves and train Copilot on their internal source code just as they do with the public open-source corpus. That would be a strong statement as well.
