I think a part of the “giving up to reddit mods” is the hopes that it will incentivise the reddit mods to push their subreddit to the community instead of trying to keep people on reddit just to maintain power.
Personally I have made several communities that I enjoyed in reddit. While I dont mind modding it’s kind of a pain in the ass as well though.
Agree with the Synology recommendation for a simple starter. Though personally always recommend the 4 bay.
