I think that's exactly what they should do, if they're serious about this: just find a way to offer everyone the whole internet for free. If something must be compromised, then compromise speed, not access to sites. Sites that want to reach poor people would just have to practice draconian bandwidth discipline. At least that way, sites could opt in on their own terms, rather than having to kowtow to some consortium of rich people.
