Sounds like Windows is also to be banned.

OK, to be fair -- any complex piece of software is vulnerable and most
commercial programs are closed. It's also a reason for censoring  
books that
spread bad ideas.

But then this is the country that was protected by the Maginot Line.

The virus problem is real but needs to be addressed by limiting the  
damage
of errors whether they be due to commission or omission.

Picking on a program that seems least likely to cause these problems
doesn't pass the smell test.

The French government's decision refers to "network security". Let's
not forget that:

Skype is a closed and 100% proprietary product that can do with your
computer whatever it wants once it is installed;
it uses port 80 to circumvent firewalls in totally inappropriate way
that could bring down the whole Internet if Skype was more widely used.


I am terrified by the idea of a rogue party being able to hack into
Skype and using it as a vehicle to launch a viral attack.

According to http://www.01net.com/editorial/289360/telephonie/skype-
banni-des-facs-par-la-securite-nationale/
the French government has banned use of Skype at universities. The
purported reason: it's insecure. http://www.oberle.org/?p=122 points
out that the real reason may be that it's too secure. A third possible
reason, though I'd have to know more about the funding model there:
someone is losing money because of free phone calls.
