Not saying you are not honest, but for others it is hard to verify a throwaway account. Or trust, for that matter, if all comments posted so far are made fiercely defending Google practices.

Suppose you left Google for a google-affiliated Reputation agency, then your disclaimer would be correct, but your comments might be fishy. No way to know. In a general sense I wonder how many of such agencies operate on HN to give positive twists to discussions that may hurt brand image.
