What about the hardware itself?

I will be more impressed when they build their own processors, DRAM, disk drives, etc. Of course, they will have to mine their own iron and other raw materials, and make sure they do that using libre excavators and transport and furnaces and so on. Then publish it on their own libre internet ...

Make sure they don't use power from the proprietary grid. But if they use solar power, better make sure those components are all libre.

Point is, at some point we depend on others. Purity of the sort they describe is at the limits of possibility, but hardly pure enough to satisfy real purists, thus making me half wonder if it isn't a Yes Men farce sponsored by The Onion.
