I think you overestimate the number of people who want to so lock themselves into a particular provider that they would use that provider's auth systems.

There are lots of different use cases for lots of different things. Since Cloudflare doesn't have the compute-type services that AWS has, rather is more specifically aimed at web-serving type services, I think their design here makes a lot of sense.

As a user that Cloudflare would target (someone who works on web sites and web-based apps), IAM is an annoyance to me that I would gladly not use on AWS if I could just toggle it off and replace it with a simpler permissions system.
