Apple as official policy once warned iOS developers not to talk shit about their arbitrary app rejections to the press so I'd say they've been pretty consistent trying to suppress negative opinions.
"If you run to the press and trash us, it never helps."
Accidental Tech Podcast dealt with this recently: Apple's support and bug tracking is really low-standard, by all accounts. Apparently, they frequently mass-close bugs (e.g. after a new release) with a comment to the effect of "if this is still a bug, please reopen it". You can understand the circumstances that might've led them to do this ... but it doesn't sound great.
As someone who files an extremely high volume of Apple bug reports, that's not actually true. They occasionally close a bug with "please try again and let us know if it's still happening", but that's extremely rare. And to be fair, the last time I saw that happen, the bug in question had actually been fixed at some point in the past. I'm pretty sure in that instance some engineer said "hey wait, that sounds familiar, I think we fixed that already, but I can't find the original bug report".
