Linux is super fragmented (and generally has been historically).
If more people in Linux agreed to develop, use, and support the same distro–similarly to how most of us use the same kernel–then that distro would probably be better than Windows and more people would move to Linux.
Counterpoint: Linux would be more popular if it were the default. Despite all the marketing and walled gardens, even Malus, the trillion dollar company still makes up a measly 25% of the end user market. They are nigh meaningless on the server market.
The majority of people will use whatever is put in front of them first and stick to it due to inertia and sunken cost. Many wouldn’t even know the difference until someone explicitly told them.

I’ve seen examples of this already where schools give kids laptops running a custom linux distro for education and they just roll with it. Also, the steamdeck happened, and a lot of people loved it before even realizing it’s just linux… We should definitely give more support to companies shipping machines with linux preinstalled (even if the first thing I’ll do is another install lol)
