I say this over and over again, but I'm going to say it again. I disagree firmly with the second point because there is such a lead and usability and ease of use for popular commercial software such as Microsoft office and Adobe software. It's available in so many languages, it has so much functionality, and yes, both surpass FOSS solutions by a wide margin in functionality.
If you don't need Excel, I think Linux and libre office might work fine for a lot of people, but there are still gaps in usability and accessibility. I don't really see the same for anything Adobe does in the Linux space however.
Linux is like 90% of the way there, but these are people with jobs and families and shit. You can't expect them to spend time having to overextend themselves with technology.
I've spent a lot of time on both windows and a bit less on Linux and I can firmly say I've spent far more time troubleshooting on Linux than on Windows.
Windows tends to give me bullshit like audio crackling or nvidia's stupid fucking software. With Linux the issues tend to be far more drastic, such as UI problems with every window, or misconfigured packages fucking with the entire OS, or an entire operating system just not functioning correctly with my hardware.
A lot of this I could fix by not being such an idiot by how I use Linux, but in my defense at the time I didn't know best practices for using Linux as a general user, and a lot of internet guides sure didn't explain the dangers of what I was doing. Meanwhile, I've never fucked myself enough to need to reinstall windows by reading online guides.
I'm glad I stuck with Linux long enough that it's what I always put on my laptops no matter what, but man I would not want to put that on others, especially people with working lives.
