Which companies do actually own and moderate their own subreddits? I have always treated all of them as unofficial, even if there are employees of the company that post periodically.
Many streamers are root mods on their own subreddits. I doubt they do most of the moderation themselves, but they appoint and manage other mods. Most aren't companies, but some of the big ones have LLCs to handle their streaming businesses.
I'm pretty sure /r/Wargroove was company run (and well run) mind you. Its not necessarily a bad thing to have company run subreddits. But it should be clear when its an "official" vs "unofficial / fan-run" subreddit.
Some are pretty much modded semi-officially for corporate cucks that remove anything that might hurt their favourite corporation, even if community clearly wants to discuss the topic
