I don't mean this as an insult against the author, because of course Americans don't have to fear being kidnapped or tortured over it! But I don't think it's right to see this as some kind of hypocrisy.
Sometimes it's different people making the complaints, but weirdly, sometimes I'm not sure it is...
There's nothing strange about that either - Twitter only acts to moderate when it has context and/or gets bad press. It's no surprise that American hot-button issues are the most moderated[1] by Twitter, and less sor for heinous, explicit threats to life in a language spoken by < 1 million speakers halfway around the world, or election misinformation in Kenya. That sort of thing never gets on Twitter's radar, and shouldn't come as a surprise.
1. This is a result of resource constraints, and Twitter's own sense of self-preservation. There is only one jurisdiction that can dissolve Twitter, and is also likely its largest revenue source; naturally, that gets an outsized fraction of Twitter's limited engineer-hours and moderator-hours.
