I've never understood this idea. The US government is dangerous to anyone located in the US. The Russian government is not. It will never matter to you if the Russian government has your data; it can matter a lot if the US does.
How do you figure that? Aside from the obvious credit card data/identity theft, there is also freedom of speech persecutions that can routinely happen should a foreign actor have your data and you traveled to their country.
Example: you are openly gay on your social media posts, and want to vacation in a foreign country that bans homosexuality. Maybe you are critical of the current Chinese leadership but still want to see the Great Wall. These are just low-hanging-fruit examples.
It's misguided to be so careless with your personal data, especially with regards to foreign actors.
It's much more likely that they will use your to arrest their own citizens for being guilty by association... which is shitty, but far less dangerous than if your own government knows your "dirty" secrets.
At worst maybe Malaysia profiles a pot-smoking Washingtonian, but even then that person still has to break the law through possession...
Oh yeah, because police never plant drugs.
It does if I have to visit Moscow airport on my way somewhere.
And his mistake was trusting a friend. Not some data collection Russian operation.
If you enter that game - you know the risks.
That's a poor justification for executing somebody without trial.
As an American in the US, my special circumstances dictate that the US government is very dangerous, and the largest, possibly only, risk that I'd suffer from the Russian government getting my data is that they'd share it with the US government.
That is a painfully naive declaration.
