Heroku is used by tons of people around the world. Some of them are paying good money for the service. Given the amount of scrutiny under which they operate, what is the incentive for them to turn an algorithm into a less effective one and still charge the same amount of money in a growing "cloud economy" where companies providing the same kind of service are a dime a dozen (AWS, Linode, Engine Yard, etc)?
How does that benefit their business if "calling their BS" is as easy as firing Apache Benchmark, collecting results, drawing a few charts and flat out "prove" that they're lying about the service they provide??
I mean, I doubt Heroku is that stupid, they know how their audience doesn't give them much room for mistakes. So as nice as the story sounds on paper, I'd really like another take on all this, either from other users of Heroku, independent dev ops, researchers, routing algorithms specialists or even Heroku themselves before we all too hastily jump to sensationalist conclusions.
