> Their pricing is either free or insane with little middle ground. I pleaded with a sales rep - I'm happy to stay on the free features but give you some money for "support" but they wouldn't take my money. Utter madness of a business model to turn down money.

It makes sense to turn down money if the administrative overhead of taking it will cost more. If I have to spend a couple of months negotiating a license/service agreement with your legal department and then chase your AP people for a couple months more to get my invoice paid, the the couple of $K you are willing to pay are not really worth it. And unfortunately that how things really work.
