How are folks recommended to get involved? Contact your local Congress member? I feel this thread has a lot of passion but is missing concrete, actionable steps.
I've contacted my congressmen and I would also advocate for telling/explaining this to non technical people you know. They either won't have heard of this or won't know whats bad about it.
Let them pry ID from our cold dead hands. If a site requires ID, it doesn't get my business.
Example, Discord wanted my ID to enable certain features, I declined, I now can't use those features, fine by me. If they started asking for ID anyway, I'd say no and see what happens, even if that means they lock me out entirely. There's no universe where they get my ID.
