Probably too late to comment (what a shame discussion is so time limited) but what interests me about this story is that they call out hosting costs as the reason to shut down.

I would love to see numbers from this operation, like we saw after Everpix. I would love to understand the scale, if it really would cost so much to host it?

So perhaps the actual take away is they didn't really violate the ToS as it is written, but they got kicked out and should have known it would happen. They may have been targeted because they show competitors pricing. Either way, it's sad to lose the service, but hard to chase those customers, because the customer won't pay. They are trying to sell the IP and maybe the company, and apparently there's some sturdy tech with broad applications!

What's so tricky is the dispute isn't about API access for the latest pricing, but rather their affiliate revenue. That can be canceled for any reason at any time, so that they still get the API and could find other revenue streams is a key point. They are not "entitled" to Amazon affiliate revenue, so then the question is -- where's the story?
