Only because they have realised that they can make even more loot. They do not have to have so many developers as the open source folk are doing all the heavy lifting,imho. 😎

Eeee by gum a' do laik play on words humour 🤣

In my view, it's all a matter of inertia. No matter what a person gets in the way of hardware - desktop, laptop, Chromebook, iMac, smartphone, tablet - they expect it to have an O/S preinstalled out of the box. And when the software is obsolete nowadays and the hardware is still perfectly usable - they junk the machine and get a new one. This model has worked a treat for Dell and Microsoft for decades. It sure works for Android tablets. Of all the desktop OSs around only Linux has not gained much of a foothold in the preinstalled market. The one success it did have - netbooks - was quickly snuffed out with a horrid incapable version of Windows. I think the reason Linux never gets anywhere in the prebuilt market is that any Linux user can install it on pretty much any machine. But that's about 5% of the computer users out there. The other 95% just buy new. Look at all the pearl-clutching going on about the demise of Windows 10. At the same time, I'm running a desktop system with Linux that came with Windows Vista originally. Horses for courses.
