How does this KEEP GETTING WORSE??
This is the wrong comparison. If you painted a modified version of an existing painting, the original painter can’t take your work and sell it against your will.
Actually it’s more like you modifying someone else’s video game and then selling it as your own
No it’s not. The modder didn’t sell anything. Wanting to be compensated if somebody else makes a profit from your work that you put out for free is not the same thing as selling it.
