1)  Some chips implement all their logic in hardware, and some leave
some for implementation in software (firmware).  Why is the latter case
more problematic than the former?  IOW, you'll almost never have open
hardware - the chip is just a black box to you.  So why does the fact
that they've moved some of the logic to software (firmware) make things

2)  Hardware logic certainly can't be debugged/improved/enhanced, so
once again, why are we worse off now that they've moved some of the
logic into software (firmware)?

3)  You mention using a Broadcom card with a proprietary driver.  Do
you mean driver or firmware?  In general, your post suggests that you
may be conflating the problems with closed drivers and closed
firmwares.  The former present much more of a problem, since the code
is actually running on your system and in kernel mode, and can
therefore do do anything it wants to your system.  This is not the case
with firmware running on a card.
