I find it completely plausible that either Google, Facebook or some other installed app is listening to your conversations to develop marketing profiles. What I find amazing is that people don't use ad blockers! I wouldn't be able to tell you if they are harvesting my voice data, because I haven't seen an ad in years! It is trivial to block ads, why do so many people choose to see them?
