What never ceases to amaze me, is the absolute inability of companies like google to understand what their actions look like for somebody who is concerned about privacy. Maybe they understand and do not care, because there are many vocal critics. But having a microphone in a product and not disclosing it? If not even google can keep track of what they should tell us, how on earth do they think they deserve trust?
(Not a dig incidentally, just that at some point the pattern of behaviour must reach a point that swings Occam's Razor to malevolence being the most likely explanation)
