Well, my friend has a Pinebook Pro. He's capable of writing drivers himself and designing MOBOs for CPUs. He's actually designed a CPU and written a compiler for it.

Being able to get to the core of the system matters very much to him - being able to trust his hardware. Releasing MOBO files strengthens that trust. In addition, he can repair the MOBO himself if need be.

I suppose me and my friend represent a minority of users though.
