Some people do avoid US companies for the reasons you've mentioned.
People tend to care more about what they are familiar with. Someone in Zimbabwe probably cares more about the war in Sudan and avoids dealing with the countries involved than with the Russian invasion of Ukraine and use Russian products. Same with someone in Iran, they probably care more about Syria and Palestine, and avoid Israeli products while using Yandex.
Maybe it's hypocrisy, but humans don't have the capacity to support every victim of every war.
I have no dog in the US / Russia debate but i recognise that both have tremendous ability to affect the world. Same with China and i avoid chinese products where I can.
That said, i'm much less concerned about North Korea, compared to Russia. The latter has sophisticated weapons and military tactics. North Korea may be an evil state but its small population and economy mean that their ability to sow chaos is limited.
Exact same argument with Sudan, the Houthis, etc. Iran is in the middle of this pack but Russia is far and away the most significant danger.
We don't even have to leave the African continent do understand that people being okay with and performing genocides, waging war, etc, isn't an exclusive American trait.
