There's also business value in "good enough" that Microsoft satisfies for enterprises. You get a lot of stuff "for free" with something like an E5 license: EDR, DLP, MDM, a full cloud IAM system, and a ton of cross app magic for the lowest common denominator of non-technical employees that you just aren't going to get without spending considerable developer effort to piece together a stack yourself.

What looks like cancer to us looks like a massive reduction in operational risk to a CFO/CIO.

This is especially true if your core business has nothing to do with software or tech. Much easier to cut a check to Redmond. Microsoft is basically a utility company for enterprise now, it's commoditized IT. "Do what you do best, outsource the rest."
