Seen in the light that they have asked for feedback coming monday, it is even more ridicolous.

So I think this is about something else than hapless comments by managers. Reading between the lines, it fells lika a coordinated spin campaign to me. If you know you will face critisism, you will be better off to quickly try to set the stage. People tend to like "a winner" and people tend to want to be like everyone else. If you don't have a specific vested interest or view of something, having you facebook buddy saying "I love this company" and "great news" and stuff, you are likely to adopt those sentiments even without doing any deeper research yourself.
That can be one effect they are looking for - if you already "know" that "everyone" thinks it is a success, why would you voice your concerns coming monday?

Another effect is that if you are first in the media to declare it a sucess and "we've had no complaints", then the complaints that eventually end up in media will be seen as the odd man out. E.g. "You can't please everyone" and "people just whine". It works well online
