@bonkmaykr @xianc78 @PurpCat @RK7 >I can understand why that may not be a good idea especially if you are borrowing some media i.e. you have licensed music in your game,
Making a copy of an audio file is not borrowing, as both can have it and use it at the same time.

It's a foolish decision to use music under a proprietary license, even for purely economic reasons, as that *will* screw over future distribution, with the forced removal of such music being common in ports of games to newer computers.

If you have to delete some proprietary soundtracks from the free release, so be it.

>if you want to incentivize people to buy a legit copy to use their free source port.
If you want to incentivize people to pay you, you just ask for payment before you provide the binary and source code of the free software.
