The issue isn’t the technology, it’s that there’s more than one way to do everything and people tend to scratch their itches.

If you started a company today, you can immediately and cheaply hire people or an MSP to manage Windows PCs. I hire entry Windows techs for $70k. M365 E-whatever is $30-60/mo.

Apple fully aligned their products, so the guys running the iPhone fleet can run the Macs. They may need some higher level assistance to setup the configurations. Unless you have a lot of compliance work, enroll in MDM, done.

With Linux, other than Chrome, there’s no standard. You’re gonna need a smart/expensive person to setup things and you’re going to need smart/expensive people to operate. If you have compliance requirements appear, you’ll need to buy RHEL or something and rework stuff, which is more expensive than windows.

It's much harder for non-dev jobs where the management won't let you BYOD for whatever reasons, which could range from IT being too stubborn to allow you to keep company data on your own laptop that's not centrally managed, to everything including licenses for random 3rd party software the company is using being tied to the ActiveDirectory fleet of computers with centralized storage.

This is the reality of IT equipment in big parts of the non-dev world, and you'll have a hard time convincing the IT dept to take on extra hassle just for you to use Linux out of all hundreds of employees who're just fine with Windows.
