Everything you say would make sense... hadn't BD paused pledges for the last months. Nobody is 'throwing money and waiting'. So everything you say about dropping your sub because it's 'business' is kind of pointless, since you wouldn't be paying a dime for the content you're not getting yet. There's no 'pay-out' for him until the content is actually out. And when it happens, yours would be huge as you'll be getting a 1000+ render update for the price of a monthly subscription (which worthed 600-800+ renders in those good old times you miss so much).
Also, given the fact that his number of patrons apparently still keeps growing despite the lack of more consistent but shorter updates, you seem to be in a clear minority here.
I don't support BD, I never did and most probably I won't ever do it; I don't even like his game that much since things started to go crazier around Day 5, but I do think he, as a developer, doesn't deserve this kind of comments at all. You are disappointed with how things are going now and that's perfectly OK, but don't use false pretexts to defend your financial choices. Or, at least, carry out a better-informed analysis before making them public.
