What sort of problems would you say they have?

Votes are (to a greater extent than HN) used to indicate disagreement rather than low quality (which leads to more low quality comments); political content is allowed and encouraged (but only that which aligns with the beliefs of the moderators); many users have been banned without any transparency as to why; significant groupthink about technical topics (separate from the political content).

That aligns well with their line of thought though, which is that there is a specific political view which is desired. They're basically building an echo chamber and it will starve on the long run because it will become so specific, the chance of a new user fitting in that community on day one will become lower and lower.

Being open is hard, very hard, but it's the only long term strategy in my eyes. The rest is an illusion.

What are those problems?
