That article sounds interesting, but I don't know the situation it's referencing. "Right to be forgotten" sounds like a good idea. At least for private citizens. Although social media makes that logistically difficult to implement.

Public officials should have to waive certain expectations of privacy in order to serve, but that should mostly focus on the present and future. Maybe their recent history during elections, but if someone has changed their political views then I don't see the benefit of digging up skeletons from prior decades, especially if they've already disavowed those views.
