its not a "reasonable compromise" from the point of view that Facebook is supposedly acting altruistically, this is a 100% self interested power play.

Is someone whose wireless Internet budget tops at $0 better off with access to 1 communication tool or 0?

(I realize that "unlimited communication tools" is the best answer here, but no one provides it at the budget specified, at least yet).

if the plan goes ahead, that could very easily turn into "never provides", via facebook content lockin and strongarming.
