I do commiserate with them in the sense that mainstream market providers of PCs are 90%+ Windows distributors. If there weren’t a dozen mainstream versions of Linux, they might get a foothold.
I always like to point out that you are NOT obligated to use Windows installed on a new PC. If you read the EULA, you may request a full refund for the license of any OEM Windows deployment from the vendor. It’s tucked into some paperwork provided with Dell, HP, and Lenovo machines. If you have an old copy of Windows and you want to deploy it to your new machine, you are within your rights to do so and to request a full refund of the license cost of the newer version of Windows.
Yeah.... except that on laptops, in recent years more than in the past, you can't get software drivers for the older OS for some of the peripherals. I've had the experience of going to an OEM vendor's site and all they have for the model is the most recent release of Windows. Microsoft (I believe) encourages, if not outright forces, them to provide only the Windows 10 drivers.
So I end up on the chip maker's site, getting generic drivers. Most times I can get them to work with the older OS. But hey, I've been doing computers since the 70's, I know some tricks. Not everybody can do that. Certainly my business clients and users have me around specifically because they can't do that.
The stranglehold MS had for decades, and still has to a large degree, on the market will not go away quietly.
That said, I have a stash of Win7 licenses I can use on my machines until Jan 2020. And mostly I'm working on a Linux or Mac machine anyway. So I have little to complain about.
