In organizations I've worked for, we use AWS because it's politically correct to do so; non-technical leadership has heard how "Cloud" is an alternative to "IT" and have golf buddies that buy "Cloud" from Amazon. Technical management can sometimes be persuaded, given overwhelming evidence, that competing products/services are superior or more cost-effective but ultimately conclude "we'll never sell this solution to leadership".
