You also have to realize a lot of h-games are hot garbage, and if you find that out by PAYING for them...? And then you can't get your money back? (DLSite doesn't have any refund policy as far as I was able to find when I went looking for it, for example. Meanwhile, Steam's sucks.)
I'm in one of those first two categories in the parentheses, but even if I were rolling in money, I still wouldn't want assholes who make trash and try to pass it off as good to get money, so I'd still pirate and then give money to the people I thought deserved it.
