You’re gonna need to be a bit more specific than that, because “defends” often does a lot of heavy lifting when it comes to issues like that being discussed from a leftist perspective. Did they outright say North Korea is perfect or there was no human rights issues with the treatment of the Uighur people in China? Or did they say the situation in Korea is more complicated than is presented by the west because we’ve embargoed them for more than half a century at this point and point out how the Uighur genocides are not that different from what happens in ICE camps in the US to this day?
Bad things happen all over the world, and I don’t think China or DPRK are perfect by any measure of the word, but presenting them as the axis of evil and ourselves as the good guys is just silly. It’s not that they’re good, it’s that we’re cartoonishly evil too.
I don’t even use third party apps, but it’s fundamentally bad for the internet for big websites to do shit like this to try to lock off their APIs to only paid users even though it’s a free website populated entirely by user generated content.
