It is not the same, you are comparing pears with apples. If you want to remodel someone else's work, you have to do it for free or ask the owner for permission (Or both to be more secure). Try modifying the Baldur's Gate and then ask for money...
He's just sharing the stuff for free here, he has got 8 patrons in the moment that earn him all of 22 bucks a month.
He tried to contact GreyInu, he offered his help if GreyInu wanted to continue his game in ren'py etc..
Don't make more out of this than it is. No one is being cheated out of money, a guy who disappeared completely can't be asked for permission to work on his game.
I don't have to pay for this port, you don't have to, we still can get it here, those who have the money and want to support greengames can do so.
There's no drama necessary here and no need for all this fauxrage.
Swear to god, this is a pirate site, people here regularly tell devs to suck it up, if their games get pirated here, but work on something like this port without a written agreement by the original dev and people throw temper tantrums.
