If somebody gave you 60K dollars and said, "Now you listen and do what I want, when I want and how I want, understood?", I am pretty sure you won't.
DC's just doing that. He goes on to his liking. It's not his fault that his patreon campaign is that successful. O wait, it is -- he is just too good to not be successful.
And btw/ he already gave account to the money he makes. He started alone, and now he has a team. He started with, compared to today, poor and little content, which he now gradually improves and increases. He made this into the most successful H game ever, and still is. He did not abandon it like so many other devs but in the contrary still throws out good quality updates three times a year. And all this for free, nobody has to pay to download the game right at the release day (OK, one day after).
Agreed. Only that art is not the bottle neck and never was. DC is always finished well before release date and does stuff for the next release, as can be seen on his daily streams.
