You can look at the modlog and see that lemmy.ml has also banned people for criticism of authoritarian governments. The reddit post I linked to in regards to Tiananmen Square was posted by one of the moderators of lemmy.ml.

Tears of the Kingdom has kept me busy enough.

Unfortunately we may just be jumping out of the frying pan and into the fire. The developers (and moderators of this instance) are unapologetic authoritarians, and on their own instance they ban people for criticizing authoritarian governments. Take a look at this post from their own reddit account in regards to Tiananmen Square.

I want the fediverse to succeed. I love the idea of a less centrally-controlled approach to social media, because we’ve all seen the problems that can create. But I’m worried that the influence of authoritarian-leaning developers could be a serious problem.
