A very good cause, and I hope the day offers a chance for the issue of
hardware freedom to be brought to light. I unfortunately am limited in my
ability to participate, but nonetheless believe it is worthy of support.
That said, are you aware that testing wi-fi/ethernet/bluetooth freedom is an
issue of firmware, belonging to software rather than hardware? It's certainly
not an unworthy issue- if anything, it's probably more important, since the
benefits of true hardware freedom are still less tangible than those of free
firmware, but it is something to note nonetheless.
In any case, best wishes to those involved in events for the day, and may
freedom in all forms be the future.
