For example, their maps app on iOS won’t save locations for me unless I sign in an enable web history tracking. I get prompted every time I try to save a pin as well as every once in a while I’m case I change my mind.
It’s a free app and it’s Google’s prerogative to try to get value out of it. But it’s annoying to me that they purposely don’t implement client tech (eg, save to app cache, device cookie not tied to individual) that would make their app better for me. And that they nag with no way to turn off forever. Their app already shows ads and makes money for them, they just want more money from the data stream.
I also worry about less savvy customers who don’t understand the prompt and unwittingly opt in to data collection that exists forever. The Facebook privacy explosion of last year is an example of users who accepted terms, but didn’t understand them, and got upset when data was used in ways that upset them.
