Sometime around 2012, Windows XP started having issues on my parent's PC, so I installed Xubuntu on it (my preferred distro at the time). I told them that "it works like Windows", showed them how to check email, browse the web, play solitare, and shut down. Even the random HP printer + scanner they had worked great! I went back home 2 states away, and expected a call from them to "put it back to what it was", but it never happened. (The closest was Mom wondering why solitare (the gnome-games version) was different, then guided her on how to change the game type to klondike.)
If "it [Xubuntu] works like Windows" offended you, I'd like to point out that normies don't care about how operating system kernels are designed. You're part of the problem this simplified Handbrake UI tries to solve. Normies care about things like a start menu, and that the X in the corner closes programs. The interface is paramount for non-technical users.
I currently work in the refurb division of an e-waste recycling company.[0] Most everyone else there installs Ubuntu on laptops (we don't have the license to sell things with Windows), and I started to initially, but an error always appeared on boot. Consider unpacking it and turning it on for the first time, and an error immediately appears: would you wonder if what you just bought is already broken? I eventually settled on Linux Mint with the OEM install option.
