To keep it legal for Patreon's purposes, the funding he gets there is for Melody only so let's leave it at that. If you think he's just milking it for greed and feel that strongly about it, don't play and don't support him. For DMD, right now and not what he was getting before, his contributions are minimal compared to Melody but compared to other devs, sure he's making a little.
Right now, DMD gets minimal funding compared to Melody and I'm not going to bother to include taxes and other costs that he has to pay for both.
