He announced that you should treat his Patreon page as a GoFundMe to support his family. It's charity, so don't expect to get anything back. Adjust your pledges accordingly!
Yeah and the sooner everyone accepts that that is basically true for every patreon and subscribestar account out there, the better off we are. You are not paying for work done, you are funding a dev that may or may not spend most of his time on a game and use that money wherever he/she wishes.
If want to pay for work done, buy the completed game or at least only support devs that have payment per update and not by period. If and I do this myself support devs per month, you are basically just funding them since you think their game is interesting and you hope it gets developed or find the dev sympathetic. Which in itself is fair enough as well. Stop with being overly demanding or expecting the stars though, we all knew there would be no 2000 images update. So keep hammering on that is just as false as saying BD made great progress on game in the last year.
BD himself said already he threw many away since he did not think good enough and had not been 100% busy on game and also on updating earlier game, so expecting that just on time passed is just as irrational as expecting he now suddenly will turn a corner and gets back to providing big weekly updates. Clearly something is wrong, whether he tells the full truth or is milking or it is even a bit of both. Though I can understand if he is telling the truth it matters greatly for him personally, but for us as players it does not really matter which of the two it is however vehemently you want to defend whichever of the two you think it is, it just does not matter and will not magically make BD produce big updates again. If he is telling the truth, it will do anything but help. if he is milking well then he is laughing at you all the way to the bank. So either you are not helping you own cause if you would love updates to the game or providing amusement for him.
Expecting big heavy regular updates at this moment in time is unrealistic. Do I think he has been making good decisions and was per se best investment option for support he had over last year, well doubtful even if is well intentioned if look at a progress side. Then again enough people support also for other reasons and it seems getting out of it what they want.
