While the GNU GPL does not tell anything about privacy and protection from
unauthorized supervision, it doesn't mean everything is done by releasing
software under the GNU GPL. There are many more things wrong in the world
besides non-free software. The fact that special services can track all of
our communications and basically control our computing through some backdoors
is bad. On a different level than having a piece of software under a non-free
license, but it is still an important issue, just a different one.
I don't say any distribution of GNU/Linux should include the best measures
for privacy and anonimous internet access (as far this one is even possible).
A GNU/Linux distribution is free to invent any type of nieche for itself, a
distro for sys admins, a distro for music makers, one for people with very
old hardware, etc.
Things like Tor and PGP, OTR Messaging are not the way one should fight the
privacy problems nowadays. "There ought to be a law...". Citizens should not
be under suspission in the first place. But as long as they all are, using
special methods for obscuring ones messages and identity on the Internet is a
legit way of protesting against the crazyness.
