The infrastructure is run by private parties -- but since the advent of encryption it ought be possible to lay down some basic principles or precepts of the online denizen. "The Right to be Forgotten" is a strong step in the right direction, but anonymity sometimes makes people act rashly -- which reminds me of the need for Nettiquette. I believe the difficulty comes in guaranteeing backdoors for law-enforcement and crime-deterrence while still affording a strong level of privacy. It's unlikely that law enforcement will simply "get used to" the fact that encryption works and is difficult [and in the case of ECC likely intractable] to decipher. The alternative is state-run applications and tech-companies with cross-sectional presence of politically inclined people, or some weird tryst of tech companies, lobbying, legislation, and law-enforcement that effectively elevates tech companies to governance level without the primary oversight of elections to place them there. If there is a third option I'd love to hear it.
