Why should citizens be punished for the actions of their government? If you're an American, how would you feel about being punished for the repeated war crimes of the US war machine (bringing slaves back to Libya, Iraq invasion and more recently drone striking innocent kids in a car in Afghanistan)?

The average Russian internet company and its developers have no part in this war. I don't see why they should be punished.

It seems like open discrimination and prejudice, no less toxic than people avoiding Chinese restaurants due to the coronavirus.

It's also deeply dangerous. Pushing an adversary into a corner can lead to isolation or further aggression. America has been battering North Korea with sanctions for decades, and they're more isolated than ever. However despicable this is, if the talks and negotiations stop then you should be seriously worried.

I'm actually with you on that. Attacking a civilian building during a war is a war crime, even if that building is tied into the war effort (e.g. farms). This isn't anything new; plenty of generals have forbid cutting trees or burning farmland thousands of years ago.

However, sanctions have proven a very effective alternative to war. It's a way of punishing warmongers without anyone getting hurt too badly.

I don't know if it's ultimately effective, though. Something like this pushes both China and DPRK into Russia's corner. And then before you know it, you have WW3 on your hands.

Many russian government owned websites are using cloudlfare.

How about this: https://chinatribunal.com/final-judgment/

The China communist party has taken over Tibet, where they have implemented a police state and forced people into camps.

Same thing in East Turkistan

And now Hong Kong.

Same game play. Invade the place, liquidate/supress the population. Move your own people in.

That first and last link is really good evidence. The BBC one is the kind I normally see, but I feel they tend to be more anecdotal and highlight interesting stories over painting an accurate picture.
