I don't think there is a tipping point. People are already trained to give up their data to Google, Microsoft, Facebook, etc. Governments will share this data eventually and amass a great deal of its own curated data. People in general don't care and I don't foresee a time where they will. The surveillance era is here and it's not going away.
