The browser is called a user agent, but this shift to absolute security no matter what, no say about it is a shift to native apps, is a shift to the developer is in control, is a shift to this being Google and the sites browser, not ours, and that being done unilaterally with nearly no opt outs is the sort of mega tectonic shift that ruins this magical special unique place in software where users had some say in what was happening. We cannot pander to imagined ever worsening users forever.
It feels like the things being done in the name of security are really building an immense prison. The work being done to allow verified age and identity checking ranks up there highly in the this corals humanity, area, not giving us agency.
