I program on the side myself, not for anything crypto-currency related, but I wanted to state this as a software developer:
If I had my own project, and the userbase started making (at this point) obscene demands of the free software I provide, and then begin to pressure me with a bounty -- it would certainly rub me the wrong way. Just let them work at their own pace, and be grateful for what you have when it comes. They honestly don't own anyone a single thing.
If anything, we (as miners) owe them. Send them donations if you feel that they've helped you get the coins you have now; but don't feel entitled to updates just because you participate in the larger community, or even sent them a donation. A donation is just that, don't expect anything in return.
