Now we know why the Guvmint doesn't like Chinese kit
Official View: We're concerned about the Chinese spying on us so don't buy it
Reality: We can't figure out a way to screw with this kit to get us the information we want**
(** Because we've had to live with the "Chinese Spying" and "Backdoor" miasma for so long Chinese companies have had to demonstrate to all interested parties that their kit is clean in order to sell it. Its the same with Kaspersky's anti-virus -- we don't like it because we can't compromise it (and it keeps catching us out).)
