I don’t understand how a Microsoft team that respects its customers (and maintains shortcuts) can co-exist in an org that sees their customer as marks.
It's almost as though organizations are made of human beings who have complicated relationships, differing opinions, and nuanced thinking.
I had a negative view of MS when I was young. Then I got jobs at large orgs managing IT for 1000s of people. I don't know how else you'd do it without the Microsoft stack. I'm not saying you can't, but good luck managing whatever custom ball of knots you manage to come up with and also finding people to work on it for you. If you think open office and some kind of custom IAM solution will work, you just don't have the experience to have an opinion on it, IMHO.
Possibly messing with the guys who handle the money make for the loudest complaints
