There's a clear conflict of interest: moderating comments critical of the organisation who employs you can easily be considered biased to a disinterested party. It doesn't matter if there is bias or not, the possibility that people will see it as biased is enough for people to recognise it and lost trust. This kind of moderation should be done by a disinterested party, and the Google employee should recuse themselves from addressing it (just refer it to another moderator). Guess who just finished their Conflict of Interest yearly refresher!
