Is this a case of "it takes a thief to catch one"? Because looking at who is behind this, they seem to have more experience in abusing (rather than protecting) privacy and user rights.
I expect nickserv was talking about all the Googlers in the founders and investors lists. But this bit in particular really jumped out at me, for a company making a big deal about its add-free purity:
"Neeva was founded by Sridhar Ramaswamy (ex-SVP of Ads at Google) and Vivek Raghunathan (ex-VP of Monetization at YouTube)"
I can't help but wonder what clause there might be in the user contract (with teeth) that would prevent a future pivot or buyout or redefinition of the "Digital Bill of Rights" after all that juicy user data has been collected.
