I guess this is what the shifting baseline argument refers to..
Having said that, I think it's rational for almost all people to not care to give up privacy for all these (addictively) amazing tools. Most people don't do anything worth privacy protecting. Having worked in data/engineering at bigtech, it's not like there's a human on the other side reviewing what each user is doing. For almost all people the data will just be used for boring purposes to build models for better marketing/ads/recommendations. A lot of the models aren't even personalised, the user is just represented by some not-human-readable feature vector that again nobody looks at.
Hell, I have multiple Google Home devices that are always on and listening, and the thing's internal model is so basic and not-personalized that after multiple years it still has trouble parsing me when I say "Play jazz" and "Stop", even though these are the 2 commands I exclusuvely use. Sometimes it starts playing acid rock, and when I say "Stop" it starts reading me stock quotes.
