Are there really a lot of alternative Wifi chips that don't require closed blobs? Do you have a list?

Are they found in any laptop that is reasonably available on the market?

I don't think that Guix is punishing users by not supporting non-libre hardware. They are making a choice in what they develop and anybody of similar mind can join their effort.

The nonguix folks are practical. It just stinks that nothing ships with a Wifi chip that doesn't require nonguix pragmatism.
