I like the idea, but the reality is business simply can’t. Too much stuff just isn’t available on Linux (e.g. CAD), and small business can’t afford the maintenance/support costs (Linux isn’t anywhere near as turnkey as Windows).
Then there’s training costs/lost productivity to unfamiliarity.
I’d love to help people move away from MS, I’m trying to for my personal laptop, but it’s a challenge even for me, a near-40 year IT egghead (my first programming assignment was Fortran on punched cards).
My biggest barrier is OneNote. Nothing I’ve tried comes close to what it can do, anywhere near as easily. Obsidian is the front runner, and I find it clumsy and convoluted in comparison. Though the devs are working hard on it, even building tools to migrate from OneNote.
Now imagine trying to teach people who don’t understand how Windows works to use any flavor of Linux. End users really have no idea how stuff works, and shouldn’t - their abilities lie in doing things I have no idea how to do.
