I am not under the impression I have any sort of privacy on the internet anymore, other than from other regular civilians.
What I have to deal with is bots, foreign actors, and domestic actors all flooding the zone with lies that I cannot discern from the truth but that companies and the government can.
Making posting a non anonymous activity equalizes the playing field between me and governments/corporations.
If you are arguing that we should keep this thin skin of anonymity that doesn’t stop the bad actors, then I assume you just want them to keep power or that you don’t actually believe that they have managed to track our behavior.
