I think it's because it's almost never accompanied by "we may have fucked up, please help us understand how to fix it now and in the future".
It's almost always (like this time) "I'm sorry you feel that way, please spend more of your free time<EOF>", and sometimes (like this time) "[we're doing it anyway but maybe we'll make some changes]".
It feels insulting because it is insulting. The decision has been made, they just want to not feel bad about you being insulted.
