Unfortunatly, that’s the reality of how computers are sold. If customers could try out both windows and Ubuntu at the store before buying and then got the variant with that OS preinstalled, I bet more people might use Linux, especially if they saved money by not paying for a windows license.
I seldom install windows, so I also have to relearn some things during the debloat. At 10 minutes, you are basically speedrunning the windows installation process lol.
