However the platform lacks namespaces. It is impossible to compete with the first one that claims the obvious name for the subject, such as, say r/startrek The competing ones also censor heavily, so all it does is that one can now choose what particular opinions one can't express. Competing on the merits of moderation style is insignificant compared to having the most straightforward name that everyone will try first; the subreddit with such name will always be the largest.
