I, for one, am pleased to see that you can optionally turn on nonfree firmware should you need it. The FSF my bloviate, but this was truly needed for those computing at home
I don't think so. Open source hardware only specifies what the hardware can do in terms of instructions, not in which quality in terms of speed or energy efficiency.
Producing high-quality hardware would still mean that you need the means of production and that will still be the same few people as now.
It would mean tho that the firmware and drivers will be open source.
