That's really a best case and that's not counting the maintenance costs (replacing the broken/stolen scooters in particular). They seem to pay the "chargers" extremely well currently, I'm sure they're still in the bootstrapping stage and not actually trying to make money. One person quoted in the article even says he expects the reward to be lowered eventually.

I actually didn't include any costs, just revenue.
