A bit offtopic but I'm wondering what's Google's angle here, by charging so much for these kind of services. They could of course charge 1M USD per request or whatever, but then nobody would use their APIs. And if that's what they want, it's easier to just stop providing third-party access, no? I mean, obviously (?) the goal is to make money I think. But if you price it such that only very big players are able to afford it... then...I feel like I'm missing a basic economics explanation here. Sure, greed and all that, but... I am still baffled so it's clear that I don't understand. Hopefully someone can provide some light on this.
