That's a poor comparison, we are not integrating BitKeeper into the
kernel :)
Like or not, BK is used by several maintainers, including The Big
Penguin himself. There are plenty of good reasons why this doc
should be in the kernel source, only a single, lone reason against
it: some people don't like _talking_ about proprietary software in
the kernel sources.

He is the gatekeeper. The kernel can be considered his, too, because it
is on his judgement that changes are accepted and rejected. If he uses
BitKeeper, and some maintainers find it easier to use BitKeeper, that's
a far stronger implicit advertisement for BitKeeper than some doc will
ever be. If Linus stopped using BitKeeper, that would provide incentive
for other maintainers to stop using BitKeeper, which in turn means there
is technical merit in the removal of the BK doc.

The doc is free by any standard. The _subject_ of the doc is not free.
There are plenty of documents talking about proprietary software
which are free, covered by the GNU FDL if not the GPL or some other
free license. Separate the licensing of the _subject_ of the doc,
from the doc itself.
I simply don't see a comparison at all. Closed source and binary
modules by definition hides IP from most. The doc is hiding nothing.
I don't think it will accomplish anything, but if it satisfies you or
others, I can change the doc's license to GNU FDL.
What matters to me is that other free software contributors are trying
to dictate what we can and cannot _talk about_ in the kernel sources.

The nature of the endorsement is implicit when BK is used by kernel
developers, not when a doc is present.
I'm very open to suggestions about combatting the notion that BK
is required for kernel devel. Removing this doc may satisfy a few
people, but (a) it does not address the fundamental disagreement,
and (b) it is a slippery slope when we start removing docs because
we disagree with their subject on ideological grounds.
Even if I was completely anti-BitKeeper, pro-100%-open-source,
I would find Daniel's patch troubling because of "(b)"
Kernel source is no place to start drawing strict notions of what is
acceptable to discuss. I weigh that assertion above a token gesture to
the silently-seething developers that does nothing to change the real
status quo.
