I am sure Apollo would be happy to pay for the use. but what they want to charge is insane. not to mention they offered the API free of charge and now they want to charge. the user base itself was increased thanks to 3rd party devs
not to mention you could have different tired access to the API's since you can throttle the requests....
$12,000 for 50 million requests does not seem "insane". Are there 3rd party Facebook, Twitter (now), Instagram, Snapchat, etc. apps? Not really. Developers were never guaranteed free or even any usage for life...
