I probably, shouldn't say anything, haha, why feed the trolls, but
monkeyposter_7 is one of the least milking devs here. His release schedule is pretty consistent, and the amount of content per update is respectable. Other points are valid of course, about the change in appearance of certain characters, the direction of the story, which may not match everyone's taste, etc, but milking? Not at all.
I try not to ever use the term "milking" because it implies misrepresenting the development cycle to the paying supporters, and developing intentionally slowly or not at all to keep the donations coming over time, and then continually coming up with false excuses to try to keep the supporters from leaving. Eventually, the ending will be rushed or the game abandoned when too many supporters leave and the dev feels like he's gotten as much out of his supporters as possible. This is actually pretty rare around here.
Pretty much every time someone says it on the forums, the truth is just that these games take a lot of time, devs are mostly doing this as a labor of love in their spare time with not much monetary compensation, and life happens. I bet if someone were to calculate the monthly patron numbers, minus Pateon's cut and credit card surcharges, divided by number of devs per game, and hours of work, very few developers are making anywhere near $7.25 an hour (US minimum wage) doing this.
I think "milking", if you use it at all, should be reserved for the few devs pulling in $20,000+ a month and releasing a few hundred renders every 6-8 months or so. Then I think it is a valid criticism (i am looking at you ICSTOR). But of course, those few devs never read the forums here because they are hiding out hoping none of the fans asks them too many questions, because they don't want to be exposed. And really, all support is totally voluntary, so if thousands of users want to support these few devs even though they never release anything, of quality anyway, than who am I to complain really. I've never given those few devs a dime since I prefer to support devs who are developing story-focused, and generally underappreciated games, that I feel could really use the support.
