When I last tried in a small pilot program, it was incredibly primitive. Linux desktops were janky and manual compared to Active Directory and group policy, and an alternative to Intune/AAD didn't even seem to exist. Heck, even things like WSUS and WDS didnt seem to have an open version or only had versions that required expensive expert level SME'S to perform constant fiddling. Meanwhile the Windows tools could be managed by 20 year old admins with basic certitifcations.
Also, GRC and security seemed to be impossible back then. There was an utter lack of decent DLP tools, proper legal hold was difficult, EDR/AV solutions were primitive and the options were limited, etc.
Back then it was like nobody who had ever actually been a sysadmin had ever taken an honest crack at Linux and all the hype was coming from home users who had no idea what herding boxen was actually like.
