I have no problem with people quitting dev or moving to some different device, that's their prerogative.
The problem is that these people claim that the next version is right around the corner, disappear, re-appear to say that the next version is indeed coming, then disappear again. Remember that these rom is sold behind a paywall. Call it what you want (donation), but when it comes down to it, this is a business selling products. I don't like doing business with people who make promises they can't or never intended to keep.
Real free software is not developed like this, but many here seem to treat these rom businesses with the same respect that they do actual community projects. IMO they are trying to have it both ways and you people are giving it to them.
