I'm not making an ideological assumptions there. I'm just referring to the status quo. The proposals I've seen are along the lines of "let's ban or add obstacles to advertising-based models", not "let's build a publicly funded Google search". I'm not saying the latter is an impossibility, but it's a much larger undertaking, and if you do the former without the latter, the effect will be as I said above--the poor lose access.
