Thanks for the reposts, I will expand a bit.
Censorship is about wars of perception. Perception is the code we run within our minds. This code needs to be free and sovereign, oriented toward evaluating the world around us based on the proof-of-work that our senses and logic can provide us.
This process of perception must be free and voluntary and can't be allowed to be centrally controlled, for a variety of reasons.
The point of censorship is preventing individuals from communicating particular information with others; to prevent certain changes in perception.
Governments are naturally motived to control how public opinion forms, in order to preserve their power. It is perception that fundamentally backs government power. A loss of favorable perception then is the greatest threat to any established power.
Social media bans are a spectrum, from shadowbanning to full banning. The point is the result; reducing the reach of certain opinions, be it openly or more hidden, to prevent certain changes in perception among a population.
