I don’t think that’s true, correct me if I am wrong though. There are still other requirements you have to follow for the GPL3 license if you wanted to distribute it legally.

Anyone is free to build it themselves. Someone could even distribute their own build from the same source under a different name completely legally.

You could just as easily in the spirit of this community do it with the same name and code, same way they do it for cracked games. Don’t tell me it’s not done because there are security concerns, you have no way to tell if cracked games contain secret malware in them yet people still distribute and download those.

They bank on users being lazy and then pay for the convenience.

And also pirates to not outright rip them off, which seems to be working for some reason…
