You personally? No idea. You probably don't. But many (most?) businesses use AD and Office and aren't particularly interested in migrating to alternative solutions.

Yes, Microsoft focuses on the customer (corporate IT), not the user.

This is how the iphone was able to nuke windows phones which were designed to meet the needs of IT

I mainly work in startups. None of them in recent memory have bothered with AD or Office. Okta and Google Workspaces take their place.

Those MS problems have an “IBM mainframe” problem. New businesses won’t choose it.

That’s why I say “why do I want them?” If I was starting a new business I’d have no reason to use them.

O365 = teams, docs, outlook, etc. workspace tools

AD = identity, access, privileging, SSO

I know what they are. No company I’ve worked for recently used them.

In my mind they’re legacy business products.

Sure, most businesses use them, but I don’t necessarily believe that is a forever thing. At one point most businesses had mainframes.

Refuse reality at your own peril. These tools are actively used at scale across most enterprises, and likely will be for the majority of your career.

How many Fortune 500 companies were founded in the SaaS era?

I'm going to guess that the 5% that don't use Azure/Office 365 represent newer entrants to the Fortune 500.

71% of Fortune 500 companies use mainframes [3], and yet they are considered a dead technology with essentially no future. Do you know anyone or anyone who knows anyone who learned how to develop on mainframes in college in the current millennium? It sure wasn't part of my CS curriculum!

Small businesses represent almost half of US economic activity [1] and represent 99.7% of firms with paid employees [2]
