Honestly I think potentially a bigger factor is that there are very few manufacturers who sell machines with linux preinstalled. Very few people have ever installed an OS before or have any desire to do so.
Also there is plenty of software with no real linux alternative even today unfortunately.
You would think. Surprisingly, i only know of one non techy person in my life for whom this was the case, and even they ended up needing to use some statistics software for school after switching to linux. Luckily, they were able to get it through a school-provided VM.
People have all kinds of needs and those needs can change over time. For people who are deaf in one ear, there is no easy way to set the audio output to mono. That’s just one way that accessibility features are lacking. I know people who rely on apps like notability syncing their mac laptop to their ipad, which no app on linux can do. I know people who have specialized software for work such as VPN apps that simply do not exist on linux. I know people who do creative work for whom it would be a major learning curve at the very least to switch. It only takes one app or crucial feature to lock you out. Even I have to dual boot from time to time for firmware updates or to play games my friends want to play that aren’t on Linux.
But you better believe I’m tracking all of these issues so I can switch people over as soon as they’re implemented ;)
