There are many non-political subreddits that ban anyone participating in any mainstream conservative subreddit. I’ve been banned by Reddit for ‘hate speech’ for writing “Hamas must be destroyed”. Ultimately, people enjoy the control and they’ll use any excuse to shape the conversation how they wish.
Is this news? Reddit's owners and mods hate Elon Musk for the most part, and they've never qualms about boosting their politics by changing the app and sandbagging the opposition.
