There's far more of that, starting with the lack of a stable ABI in gnu/linux distros. Eventually Valve or Google (with Android) are gonna swoop in with a user-friendly, targetable by devs OS that's actually a single platform
That's why, RHEL for example, has such a long support lifecycle. It's so you can develop software targeting RHEL specifically, and know you have a stable environment for 10+ years. RHEL sells a stable (as in unchanging) OS for x number of years to target.
It’s not my distribution of choice, but it’s currently doing exactly what you suggest.
The problem is that Linux can’t handle hardware it doesn’t have drivers for (or can only run it in an extremely basic mode), and LTS kernels only have drivers for hardware that existed prior to their release.
So they already are the major player in this game and will have a leg up on others trying to enter the same space.
