What you do is entirely up to you even if you consider to release your own incest patch here on F95. Zorlun can't do much about it.
Hmm, yes and no.
1) I took an engagement with Zorlun. I agree it is not a legal contract, but does not mean that I intend to violate it. I basically described in some of my posts how anybody can recreate the incest part, so that people could do it on their own if they wanted to. But there is "no redistribution" engagement.
2) If then one wants to play nasty, if Zorlun is pushed too much, he may just never make Marc coming back, or never again put back naughty content Myriam/Marc, or change the way the game is built.
He may lose some more supporters (and if changing the way the game is built, increasing his workload), but it would also make it completely impossible to do that kind of patching.
If I transform my "do it on my hard disk" into a patch that is somehow distributed (and there is the issue of how, and wether can guarantee in the long term the time to do it, it is a manual thing), it would be to help the players and Zorlun (by attracting more people to support him, knowing he does the game and the images), not to get in a war with him - he is the author.
