It's nice except for the one part where he says he has some responsibility to his users. He doesn't. Not at all. That would be a one-way relationship or responsibility. If his users were paying him, then I could see some responsibility. If it's free and/or incomplete, it's the users that have responsibility when they download it: be grateful for work done so far, make sure it works as intended, and so on.

FOSS developers shouldn't feel guilty or responsible in the slightest for their users unless their users' success is part of the developers' lifelong goals. For instance, protecting liberty by making sure Tor and GPG work properly. Otherwise, screw them if they want something done but won't contribute anything back.
