Two main points:
- no one unified distro to keep things simple (thread OP)
VS
- people don’t care. Someone else needs to advocate, sell, migrate, and support (medium term) Linux (whichever distro they want) for the intermediate term (few months at least) - thread response).
I think a lot of the 97% desktop market share is like this, instead of the hands on 2-3%.
You don’t need to learn Linux to use it.
Just download any mainstream distro and it will be fine!
That is already a step too far. If it doesn’t come pre-installed, the majority will not use nor know how to install it. I bet a bunch of people don’t even know what an OS is. If you replaced windows with some riced KDE desktop on the majority of user’s computers, most would think it’s an update and would go on with their lives.
