Microsoft doesn't give a shit about Enterprises switching some employee computers to Macs anymore because they still have O365 and Azure AD (Entra ID whatever the hell they're calling it now). Hell, when Satya Nadella took over from Steve Ballmer, he cut the QA:developer ratio from 2:1 employees to 1:1. Firing half the QA people, and leaving consumers/businesses not rich enough to afford using the Win10+ LTSB/LTSC as the equivalent of QA testers on the updates.
Mac enterprise users can still use MS cloud enterprise services such as O365, Sharepoint, OneDrive, Teams, Outlook the MS other Office apps, etc... Azure in general for enterprise cloud compute.
The desktop is no longer as glamorous as it was. Of course, through enterprise licensing, Microsoft will still milk that market for as much as it is worth. They're just not as concerned about maintaining dominance, or making the user experience worse on other platforms deliberately to maintain Windows marketshare.
