Sure, that's the easy response, and clearly the attitude of typical developers.... but on the other hand, if you want people to take your product seriously, random unannounced operational changes aren't the way to go. All it takes is a FAQ, release notes, SOMETHING. I can think of no other device in history that expects people to put up with such crap.
Oh hey, we changed your shifter operation today without notice; D means "drive backward", P means "proceed to next destination", N is for "not driving anymore", and R means "rev engine".
Oh hey, new feature today, pressing your toiler lever up means flush. Down means enema.
Oh hey, regular up/down light switches are boring. Today it's press to start and up/down controls the thermostat.
