Governments tend to block things like facts about genocides they have committed and opposing political opinions. I would hope things like child exploitation could be managed at the host level.
Do you have any idea how eagerly AT&T and Comcast would block half the internet if they had the tiniest profit motive to do so? I wonder how long left wing websites would remain online if it weren’t illegal for multinational corporations to block them.
That’s the thing, they is no profit motive to block wide swaths of public viewpoint because that will cost them customers. They will quickly lose business to a competitor who doesn’t do that. (Local monopolies aside, which is an entirely different problem).
I wish you were right, but you’re not. Internet providers have monopolies because the cost of laying fiber or launching satellites is so high. That’s precisely what the argument over net neutrality has been about.
