It is somewhat counter-intuitive, and I'm not stating an official
position here. But I do think my reasoning (see below), is consistent
with the current thinking of the FSF.

Indeed, we do think that adding more restrictions technically is a big
danger. At the same time, we think that you ought to be able to send an
gpg-encrypted copy of gdb to your friend in Unfreedonia, where debuggers
are banned. This could fall afoul of the anti-drm provision of the SA
licenses, because the Secret Police couldn't read the document.
Trying to allow good encryption and disallow bad encryption is one
reason we're having trouble addressing the Trusted Computing problem in
the next version of the GPL.
So, I'm not making an official statement here, but I believe the FSF's
position is consistent with my own.
