Technical people have been gleefully eliminating anonymity on the web for the last 20 years. Progressives should be the party on the side of maximal freedom but really in the US we have one neo-liberal party wearing two different disguises.
The problem is normies don't operate under assumed anonymity. So when the hordes of unwashed regular people joined the internet they wanted their face everywhere. People were shamed out of their handles. Some people gave up their anonymity to make yet another faceless bullshit blog-as-a-resume. Look at most of the top karma farmers on HN. Most of them post their personal information in the their bio. Pathetic.
> people will self-censor when knowing they are being watched.
This has been happening both in public and on the internet for over a decade now.
> Not being able to be at least pseudo-anonymous has a real chilling effect on speech and expression.
The normies would argue you have nothing to hide if you aren't doing anything wrong. The average voter, regardless of party, will happily surrender every ounce of freedom for the thought of security. Hell, I remember sometime around 2007 DEFCON became a first-name-basis conference!
> bill of rights
It's more of a bill of privileges given NGOs and PACs are regularly paying to erode the core rights granted to citizens. Either through lawfare by circumventing the courts and suing companies into bankruptcy, or by directly purchasing congressmen via donation.
What I have found in general is people who cry and complain about this kind of thing were, at one point, happy to have it happen to their political enemies. The laws that are paving the way for age-gated deanonymized internet were at one point used as a cudgel to beat their political enemies down. When the tables finally turn after the Nth "protect the children" bill, it's the other people left crying and now suddenly its a "problem".
