Government sponsored hacking was started by the CIA and the FBI. The CIA used this, to spy on their enemies and even on their allies. Russia and China are late entrants to this sector, but they have caught up pretty fast.
And that history lesson correlates with current reality how?/Did the US hack the farcical Russian 'election' (it's even more a sham then our last one) ?
China invented guns. The US and Russia were late entrants to the sector, but boy, they caught up and surpassed the entire world.
But how about that Russian hacking though?
And can we please stop using the two wrongs fallacy to describe Russia's actions? Educate yourself:
The tu quoque fallacy is committed when it is assumed that because someone else has done a thing there is nothing wrong with doing it. This fallacy is classically committed by children who, when told off, respond with So and so did it too, with the implied conclusion that there is nothing wrong with doing whatever it is that they have done. This is a fallacy because it could be that both children are in the wrong, and because, as we were all taught, two wrongs dont make a right.
Example
(1) The Romans kept slaves.
Therefore:
(2) We can keep slaves too.
This argument commits the tu quoque fallacy because it assumes that if someone else does a thing then its okay for us to do it too. It does not follow, however, from the simple fact that the Romans kept slaves, that there is nothing wrong with keeping slaves. It is plausible to think that the Romans acted immorally in keeping slaves, and that we would act immorally if we followed their example. The conclusion of the argument therefore does not follow from its premise.
