They block traffic reaching your website, not the other way around. For a poor, nitpickable analogy: they keep the bad guys out of your home, but they don't want to take away homes from the bad guys.

We all know the definition of "bad guy" shifts every four years or less

I get what you're saying (they're affording access to info, not access for people) but you can't have one without the other.

With your analogy, they aim to keep the "bad guys" out of all homes, which is the same thing as saying those guys can't have homes. Also the "bad guys" group you're referring to includes, like, my cousin Jake because he accidentally crashed his pushbike into a car once when he was 6, but doesn't include Adolf Hitler for some reason.
