Love this - I can almost imagine the convincing for other companies wasn't even needed when they realized a small binary size and comparison to competitors would net them more business. A perfect little solution for triaging issues between services and comparing solutions.
That was indeed the logic. The two main commercial solutions included (Binary Ninja made by Vector 35, where I'm one of hte founders) and Hex-Rays both pay for all the hosting costs. And it's not particularly cheap -- there's a fair amount of compute to drive the decompilers especially as some of them are... not very efficient.
