You seem to be suggesting steam moderators are somehow employed by the developers to manage and facilitate PR. As far as I am aware these positions are voluntary and they are really tied more to steam and their forums as opposed to the game or the developer. I don't think the steam moderators really have any more information about the game development, plans, etc than the standard person they are just more aware of what's been said by the developers here or on other official channels from the developer.

Honestly if you want to communicate directly with the Devs I would recommend Twitter or on their Discord. The moderators here are just trying to keep the forums manageable and not have 25 different posts ♥♥♥♥♥♥♥♥ about the same thing. The developers have said in multiple places (including here) that Mistlands will release in 2022 yet we multiple people asking about it every day.

If the devs choose not to answer questions there is really nothing they can do about it. My guess is the questions you think are unanswered are really answered and you just don't like the answer.
