Which firmware must be locked down? I was under the impression that is
just retail end user devices, is the suggestion that chip manufacturers
will not be allowed to sell parts to people who might make a non locked
down device? Does that include if they don't supply firmware and the
user writes their own/reverse engineers others? Sounds like a road to
future regulating all rf hardware sale (stop people selling rp
connectors as it's letting them circumvent the antenna limitations they
were designed to impose?)

Given the interference that caused this is a few incidents a year
compared to the millions of units sold and that those cases were
either bad users or caused by faulty devices it seems that the
lock down would have to be total to prevent future incidents. Quite
impractical.

It think it would be cheaper and quicker to reverse engineer drivers
for others hardware. Even if the cost could be covered to build it'd
lag commercial products by years making it a difficult sell, and likely
subjected to IPR claims from current manufacturers

That could be an interesting project. It may not help but we have
an FPGA MIMO implementation we may be able to release to such a
project (it may be unsuitable though, we've been making radio cameras

Yes, and if the lock down expands to chips too would have
the same problem
