There is a category of companies that doesn't try to be a content arbiter. Common carriers, utilities, other services that have an obligation to contract. Of course the "contract" with SNPs is that you "pay" with your eyeballs falling on adverts, and the ads in turn don't want to be anything like common carriers. So turning any web service into something like a common carrier would have interesting knock-on effects.
