And I'm sorry to repeat myself, but I don't think there will be a significant move to Linux on the desktop until the big commercial players port their applications to Linux. The existing Linux desktop applications are just not good enough.
Well I think that's a very personal matter that depends on a)what you need to do; b)laziness
I personally use almost exclusively Linux since about 2002. Found that i can do all I want to do. Things like FreeCAD made me pulling my hairs more than once, but, hey, with use comes learning, At the end of the day, it's enough to do what I need it to do, including things like FEM that are not available on windows offers, at least for free. By using Debian, I get easy, hassle free access to rare and quite fine apps like a virtual wind tunnel from a MIT professor, a fine, free GIS which isn't emasculated, or a mapping app for caving that is able to redraw the contours of a cave when a polygonal is corrected (which saves A LOT of work). Installs are really easy, apt does install any dependencies for me, and I never had any antivirus making my system slow. So, if you are happy with what windows gives to you, fine. It just isn't enough for me.
I have friends that used to have windows for just email, Internet and spreadsheets. Problem was, they were guys and, so, they liked to look at some boobs every now and then; after that, they usually called asking for help because their PC got syphilis, gonorrhea and AIDS. They were scared to have linux because of substituting libreoffice calc for excel. Most of them rapidly saw it was the same since hey didn't use any macros. An easy migration and now they don't need windows, which a) allows them to watch boobs recklessly, and b) allows them to use old hardware. One of these friends still uses one of the first dual core AMD athlons, which I got for him, for free because it was already "too old" in about 2015 IIRC. So, if you like to be bothered by all sorts of viruses, have your PC slow because of the antivirus, and have pockets deep enough to upgrade your hardware each time microsoft thinks it's time to milk the cow again, fine. I just don't like that, so took another road.
On the other hand I have seen a low-ranking local female officer ranting at tech staff because what was Ctrl-P on Excel became Ctrl-V in Calc, and that was obviously unacceptable. Well, laziness is still a personal matter.
I think privative business model has more to do with slow Linux adoption on the desktop. You can't do any serious paid, professional printing work without Pantone codes, and they will probably never get into Linux, because Pantone is privative, unless Pantone gets interested in having it working under linux. No one is going to do it for free. Pantone privative business model was already a thing in the 90s. So far this has not changed. Better get a Mac for that.
Of course, you don't want to waste all the work you did to learn to use the apps you "need". I can understand that. But I'm glad I took the work to learn how to do useful work with apps that are really worse, but allow me to use an OS that is free, runs faster, safer and easier, can use much older hardware, doesn't compel me to signing into any vendor account, and doesn't spy on me.
