I think that is inevitable as long as the top N companies enforce their morals and standards on consumers all over the world.

If the world could agree, we can legistlate these companies to be neutral and grant then protection from some state lawsuits if they don't enforce standards that aren't globally agreed upon (by the UN for instance).

It will be tricky because that means admitting that internet companies are their own independent states and many countries will not be happy with that.

I think of it a little differently. I think as long as their is a potential to exert political power via the internet, then governments will strong-arm companies into doing their bidding.
