From what I know about Google, they are serious about least privilege type of stuff internally and employees dont get arbitrary unbound access to systems or data.
Just like the OP I have first hand info on how atrocious Microsoft’s internal privacy controls are.
The later versions of Windows are just ad space for Microsoft to advertise.
Azure is the worst of the 3 cloud providers. Horrible developer experience and documentation and reliability.
That said, I would still take Satya’s Microsoft over Balmers any day
Don't forget security! Multiple serious and extremely trivial cross-tenant security exploits only in the past couple of years. AWS and GCP have had none ever, the much smaller OCI has had one.
