Of course it can happen that the developer doesn't adequately address the users' concerns, perhaps it's impossible to do, or more likely, the developer wasn't really listening. So yes, the end-runs could be understandable. If the developer understands the user issues, and takes the trouble to mitigate the situation, it's a lot less likely end-runs would be attempted. Any case, the smart developer knows there's a message intrinsic to end-runs, something isn't working and the developer's part of teamwork to see what can be done about it.
