I agree. Also, it's not like the whole internet will be under ID check. One can still opt out and don't use the main stream social media? My hope is that ID check is targeting never ending feeds of crappy content.
That said, I am very concerned about how things work privacy wise today (even without ID check).
The privacy tools that are working today will be much easier to block. Hence, any activists and journalists that the government dislikes will become even more vulnerable. We need to fight this and not give up.
