Let’s be honest, did the Devs ever really “like” the forums? Do they really like Reddit? The recent blue post on Reddit cast some shade that-away… My feeling is some Devs like to interact (it’s on their own dime after-all) some probably don’t.
Reddit is a safer place for them to post on simply as it’s not offical and they can’t really be held accountable for anything said there. That’s just my thoughts, I’m not saying I’m correct about this, but it’s somewhat logical. You only have to look back at the Blue posting on these forums when they were humming in 2018, very little Dev posts when there was a high volume of quality posts to interact with.
When given this choice and riches of quality posts, they mostly decided to post in the inconsequential threads that many claim are the reason they don’t post now.
