Let's put it this way: Just because they live under an oppressive regime doesn't mean we should be mean to them and keep them isolated in their evil bubble.
Say, many would agree that Han people in China are oppressed. They have a ton of middle-class citizens who are free to leave the country, they just don't want to permanently due to not thinking it'd be better.
Same applies to Threads, though maybe a stronger case for leaving.
I’m not having a conversation that compares people signing up to their favourite social media channel with people who suffer systemic discrimination every day in their lives.
