10x in cost isn't necessarily the most important factor to a business.
From an individual's perspective, that's hard to understand. To a business, it really isn't that difficult to justify the cost.
One of my criticisms of HN commenters is the inability to empathize from a company's POV. Just because it doesn't make sense to you doesn't mean it doesn't make sense!
Companies (especially big ones) have different priorities than individuals. I may think it's stupid to 10x infrastructure costs by using AWS. A company may say "that's 1% of my budget, and it keeps my development running smoothly and developers happy with the familiarity and flexibility. I make that 10x cost back in 30 minutes, every day. Not worth optimizing."
