So I just ran across this, after leaving a comment in that same thread. Posting it again here to try and add some sanity back to this discussion:

Okay, but there’s a line here somewhere. Pushing for new features and complaining in the issue tracker that a bug hasn’t been fixed soon enough is absolutely entitlement. Expecting someone to follow through on their word and release the source code is another thing entirely. Especially if they make the decision to stop working on it.

Go check out this EoL statement from the developer of Nomie. He open-sourced the code without even being asked too.
