Apple broke a lot of peripherals and software by unannounced unnecessary changes.
We had to completely rewrite a USB firmware stack - and being firmware, it had to be installed on the device by the end user.
Using Windows, because Apple had broken the USB stack so Macs couldn't see it to update it.
There have been a lot of similar breaking changes in many areas on macOS. For many companies the cost of macOS just isn't worth it - do you burn six months every year simply keeping it running (and likely breaking it for older macOS versions), or spend that time on new features and products?
Microsoft has historically been very good at adding OS features without breaking existing hardware and software. If they fail at this then Windows will die - if my users have to learn something new then they might as well learn something free, eh?
