They freaked out at Heroku with decent reason because it was costing them money, but if they ran their own infrastructure, that would have been a total non issue and at the scale they are running, why ARE they using Heroku? Are you arguing that what Heroku was doing wasn't wrong? I'm not sure why this behavior hasn't put them in the same category as Zynga, Groupon, Swoopo, and all the other companies the tech industry loves to hate. Comments on every single RapGenius post on HN have been filled with vitriol toward the founders, their attitude, and the culture they foster.
