No, those derivatives are damage.  While their hearts are in the right
place, they cause data loss and security holes by at least making people on
Intel and AMD machines use known-buggy microcode.

Yeah, opaque encrypted microcode can be used to sneak in new backdoors,
but that doesn't make past bugs (and "oh, those foul hackers found one of
our backdoors, it was a honest bug, really!") any better.  At the very
least, you get new TLA-only backdoors while those fixed are usable by both
TLAs and any random punk.

Likewise, closed firmware for your wifi card is evil, but still strictly
better than the same code burned into ROM: you get some bug fixes, and can
go back to a past version.  Sweeping non-free code under the carpet doesn't
help in any way -- if you have to use it, it's better kept where you can
see it.

The biggest reason for me to avoid non-free code is that neither me nor
anyone among us can fix problems.  And those derivatives you're talking
about tend to reintroduce this problem for political reasons (GFDL with
invariants).

Even Debian is not without fault here: for example, the ftpmasters accept
such a blatantly non-free licence as AGPL[1] into main.

I don't think any such extra infrastructure is needed: what we have already
works well, at most it could take some clarification in the Policy.  I
believe the model that's in place for apt is worth adopting for browsers,
media players and such.

That is:
* no new non-free code is ever installed without the user's consent
  ("new" defined at package granulation, allowing splits/etc)
* it's not even proposed unless the software detects that such non-free
  parts are actually needed
* once a piece of non-free code is installed, it should receive updates
  unless explicitly configured otherwise

The last part matters because of recent Chromium issues.  Of course, checks
for updates should be done in a way that minimizes privacy issues (which
Chromium's upstream loves to maximize), but defaulting to no updates at all
is irresponsible.


Meow!

[1]. AGPL fails FSF freedom 0: you can't reuse snippets of code from an
AGPLed project in anything networked that has no, or cumbersome, ways to
pass advertising statements to the user (such as, eg, an IMAP server).
It also fails the Dissident Test: take a blogging software with
steganographic features, that you provide hosting for, for two classes of
users: fellow dissidents, and public at large.  The former receive the code
(both binaries and source), the latter do not.  Even revealing the existence
of your changes is a serious risk for the life of you and your friends.
Regular GPL has no such problems.

You might read my words as a sort of FSF bashing, as both bad licenses are
provided by them (GFDL and AGPL3), but regular GPL is generally much better
than BSD/MIT: it emulates a world without copyright much better, as in such
a world we'd have decompilers, etc.
