I personally "feel" (because I can't really form a hardened ideology around it) that the closer things get to infrastructure, the more neutral they should be. In other words, the more difficult it is to spin up a competitor to Company A, the more Company A should actively work to not censor or shape messages or ideas.

I also agree we cannot enforce decentralization. My hope is that one day, we can see the benefits of it as a people and collectively decide to go that route without coercion of any kind. Wishful thinking, probably =]. That won't stop me from trying to convince others of the benefits, though.
