I wonder if a MSFT employee was typing a response to you, but accidentally clicked edit on your comment and it overwrote your content before they realised what they have done, then panicked and just hit submit.
Particularly considering his comments were just echoing all the other comments in the thread - and the message "hello there" is strange and doesn't really make sense to me (if they have the power to edit a post, they probably have the power to delete it outright, which would have been less suspicious and not generated this post).
-There are no MS Employees there (but professional Call/Text Centers)
-MS gives a *it about your opinion (as every big IT Company)
-But MS wants you to feel that your part of the family (inclusive developers developers!!)
You're better off shouting into the void than expecting to get anything useful out of those channels.
