The long tail of AWS customers is pretty rocky and is a revenue risk as well. Why deal with folks that can come and go so quickly when stable, sustainable revenue is what matters more for a growing company? Most AWS consultants and devopsy / SRE types IME are hired around the lower to mid 5 figure monthly spend mark depending upon growth to warrant their cost and at that point $50 / mo is hardly even mentioned. Heck, even hiring a consultant instead of hiring engineers with experience in the first place is a bit of an old school thing and implies legacy or not a start-up kind of businesses (lift and shifts, that is).
Those cloud users can have the same benefit by spending a fraction of the price. That's the point. The question you're trying to ask is whether the added value being promised justifies a price tag that's 10x higher than the ones offered by established services.
