In theory, schemes like this are a good idea. In practice, not so much.

Unless the list of sites being blocked, along with the reason is public information, I personally wouldn't touch it with a bargepole. Its too easy to implement censorship by the backdoor this way.

Theoretical example:
Add the domain of a small fledgling rival to the list. Their site disappears off the web and they have deniability, as nobody can prove its on the blacklist, since the blacklist is not public information. If all the major schemes do likewise, potential rival dies at inception due to almost nobody being aware of their existence.

The blacklists of such schemes need to be subject to public scrutiny to avoid the companies runningg them, being able to abuse them, and for all their good intentions now, they can't honestly say what will happen in the future. Best not give them that opening chance in the first place.

I will be opting out of the governments firewall when VM implements it. Not because I like or want porn, but because I don't trust what other content might be added to it.
