Flock promises all sorts of safeguards and ethics around, y'know, the law, but the reality is their perspective is "it's not our job to tell you that you can or can't do something, even if we know for a fact that you can't".

Reminds me when I build health insurance claims management software (pre-ACA). "We want to mine the database for familial history of conditions, based on familial claims and ICD codes".

"We can't do that."

"Why not? It's all in the database."

"It is. And we are legally forbidden from running such queries."
