We have authorities willing to persecute. The difference is just that such authorities are no longer owned by the public. Social media companies are the authorities.
To elaborate a bit on why I say this: Since Social Media became uniquitous as a communication medium, I have found no more helpful way to process this in just political terms than to recognize the role of social media as a virtual urban plaza. For the last 7-8 years that I have used that metaphor, it has persisted in leading me to what I believe is the most respectable and ultimately healthy assessments of the terms it should operate under.
Interestingly, the plaza had a more complicated relationship with anonymity and pseudonymity because, outside of one’s community, one could not be recognized or traced. Nonetheless, learning about the history of this is surely helpful here.
