I'm sure there are absolutely brilliant people working at Azure. I think the overall system is very badly architected and I don't know what it would take to salvage it. Infra security is a lot easier to do when you have a system that has mostly solved it already, and I'm not saying GCP and AWS are perfect, but "security is mostly solved" is a decent description of their systems, I think. Of course it could all fall over tomorrow, but I'd guess that's a lot more true of Azure.
