You are right. There is almost no malware on Ubuntu. But again it does not need a malware to be rendered completely unusable. A mindless update to a buggy version of anything from the repositories will do.

Did anybody care to read the whole article and found that the $2000 car does NOT have power steering, ABS and airbags?

Anyone cares to read the referred articles? This is only a move of a insignificant local government and is already criticized in many Chinese forums and online media sites. As a big country, things much weirder than this happens all the time. It is surprising why it gets singled out here. Yes, Chinese government heavily filters Internet connections and suppress any sites that it sees inappropriate, but it does NOT have to force linux on Internet cafe simply to spy on citizens. Believe me, it is much easier and inexpensive to spy on Windows machines. My suggestion: next time before you bring up something about a monarchy/communist/evil China, do some research.
