I am sorry if I am being rude... Don't you think its a huge issue of trust?. The data can be sold to insurance or advertising companies ( no HIPAA or other laws to protect the data here ).
Yes personal data protection it's a good thing to think about, maybe not the highest prio problem though.
We call it Sandy with special offers. If you'd like to pay extra you can get a special-offer-free experience. If you don't like the idea of any data collection you can just buy a cat litter box and have your own Sandy (without the added features).
Don't see how this is an issue.
