First this as context:
“Today some Google Home owners reported hearing something extra when they asked for a summary of the day ahead from the smart speaker: an advertisement for the opening of Beauty and the Beast … The ad was delivered using the regular Google Assistant voice, so it blended in seamlessly with the other My Day information (weather, calendar appointments, etc.) … When contacted by The Verge for more information, Google denied that the audio snippet was actually an ad … “
then this:
“Online advertising and privacy has always been at war. Listening in on your conversations because you placed an always-on microphone in your home is just the next obvious hill to capture. Google has already normalized reading your emails for context-aware advertisement. Listening to your dinner conversations is just a natural jump.”
