I switched to Linux about ten years. I basically got tired of having an OS I paid for (in buying a computer) not really be "mine". Lately, I have had few problems installing and running Linux on the various cheap laptops I've bought.
Ubuntu with a Mate GUI "just works", has all the software I need and lacks BS like the Windows 10 interface.
I don't really think there's any objective barrier to using Linux for a significant percentage of people - people who don't need Adobe Creative Suite or similar monopolies. But this is the same population who probably won't both doing something unusual given they have no strong motivation.
