To be fair, noone is obligated to give him any money. Just take a look at the update history and decide for yourself if this is something you are able/willing to support.
If you decided to do so, fine. If you decided not to, also fine. If you gave someone money without any consideration, then you probably can afford to do so, and or don't deserve to have that money in the first place.
If you did so persistently for a prolonged amount of time expecting things to change, I do not know what to tell you.
Maybe look around and see what's going on in the world. It's not anyone's job to tell you to stop giving them free money. If you were in his position, you probably wouldn't either.
