For starters, they're leaking this information to Google.

After that, they're presumably subject to subpoenas. And they or an acquirer altering the agreement. And there's interpretations of "give away". And the inevitable data breaches.

I see no identification of who runs it, which doesn't seem consistent with their stated philosophy of "transparency and accountability", and might affect users' ability to hold them to their privacy assurances.
