Did any firm that spends $100k/month not realize that they were underpaying for support at $50?

If I'm spending six figures on your product I expect at least a certain amount of support to be free.

You expect wrong. Standard support fees are usually in ranges of 10-20% of the price that you are paying for the product. And it makes sense - costs of providing support are not constant why should their price be?
