I'm ambivalent about Medium's approach. All in all, I do think that you get what you pay for. FB's negative impact is due to their ad monetization strategy. Medium is trying to charge through subscriptions vs advertising, and pays according to time reading vs. impressions, so is much more aligned with readers than non-subscription media.
