I got the idea but not convinced so far. Even if it is true I don’t think they did a bad thing. Also even based on presented factoid the link between their actions and elections is somehow thought up. How exposing a corruption is a bad thing?
The law protects personal communications but there are might be exceptions and wiretaps are legal under certain conditions. The reason? Committing a crime is not a part of personal life.
The same might be applied to hackers exposing political corruption.
Not by the letter of law but by the spirit of justice in this case.
For sure they did not violate Russian law, but you can be assured that the violated US law, and that is the relevant issue here.
If you are convinced or not is immaterial, it is an issue for the court in the US.
Like this:
In what BBC Russia says is possibly “the largest data leak in the history of the work of Russian special services on the Internet,” hackers stole 7.5 terabytes of data from a major contractor of Russia's Federal Security Service.
Leaving aside the empirical evidence that it was an inside job, the notion that Russian intelligence hacked the DNC server filled with politics and gossip, but left the Clinton bathroom server filled with classified state secrets untouched is absurd.
Then again the entire premise that the Russians ‘meddled’ in the 2016 US elections is a hoax, and the folks peddling that crap are domestic enemies, one and all.
