I believe that many internet flame wars are caused by inaccurate or imprecise statements. It is important to me to indicate the source and quality of information that I post.
It's not that your phrasing is incorrect in any way, it's that the subtext is "Management has no clue about the real world, but this is what they claim. It may not be their real motivations, or true in any way, but the statements we hear are" - a level of distrust in management that requires that sort of disclaimer is a bad sign.
Its hardly "subtext", when the last sentence is "I don't believe Google+ management is malicious, but they do seem woefully unaware of how internet-native communities behave."
(I must admit I did shake my head at that and think "even at _Google_?")
What would you have written?
