I wouldn't be surprised if some people inside Google think that way, but their margin is not my problem. I assume that anything that costs $300 comes with support. And anyone who accepts credit cards needs to provide enough support to avoid chargebacks from confused customers.
I assume that anything that includes "support" in its product description when I purchase it includes support exactly as described.
Assuming more than that is unwarranted, and assuming that free additional services not advertised are included with products because of high price is especially unwarranted.
