I am one that switched. I have Linux Mint which I use 99.9% of the time, and a windows 10 laptop that I use 0.1% for that one windows program.
I think more people are wanting to get out of the grip that google, apple, and Microsoft have over them. Many are overwhelmed because they are in so deep. It took me months to get out, which I did about 6 years ago. I never looked back though. I know people that want out, but are not strong enough to commit to switching all their services and apps.
