The main hiccup for hardware support is GPU support, and as a side effect of the bigger business being in messing with LLMs and that use case preferring Linux, GPUs are getting more Linux attention.

For example, nVidia drivers went years and years with a status quo of "screw open source, compile our driver and deal with the limitations". Only after they got big in the datacenter did they finally start working towards being fully open in the kernel space (though firmware and user space still closed source, but that's a bit more managable)
