Completely true. However if what you're doing is highly price sensitive and willing to accept downtime over ScaryBill, then this the option you all need. And it's completely (and I bet intentionally) not available on AWS. AWS's message is "bend over and we'll tell you how far and long".
Larger companies see $4k as a nothing; pay and move on. Household budgets, not so much.
