I've been in those shoes (not with Frontier, though, obviously). As a Community Manager, you basically have 2 tasks:The Lead Community Manager wasn't online since 1 month.
Nothing against Arthur, I think he is a pretty cool guy. But obviously the forums aren't a priority to them.
1) Gather feedback from the community (criticism and creative ideas) and channel it to the competent persons within the team.
2) Gather development information you are allowed to distribute, and channel it to content creators, influencers and community members.
If upper management does not want community feedback to be considered in development (which is not necessarily a bad thing, there are situations where it can be better to shield the dev team from the community) and also do not wish to release any internal information to the public (maybe because they don't have a clear plan themselves at this point), then the community managers are in a pretty bad spot.
We can only speculate, but I'm fairly sure that this is pretty much what's going on so far. We know that Frontier is pretty top-heavy, and there are various reports (starting with Ian Bell) suggesting that Mr. Braben is not always the easiest person to work with.
We know that Odyssey was released prematurely. We know that F1 Manager 2022 still hasn't been released, despite the F1 season being in full swing already and Frontier's fiscal year being about to end. We know that Warhammer: Age of Sigmar has been postponed into at least the coming fiscal year.
All this paints a picture of a developer / publisher that may have grown too big for its own internal structures. Which probably creates quite a bit of internal pressure. And which results in the company going into defense mode, where they try to shield themselves from external pressure.
I have no idea how resources are being distributed inside Frontier, but I guess that every movable chess piece right now is assigned to getting F1 Manager released. If that release is successful (and early media reports do show some promise), maybe we will see a little more progress on the Elite side in the second half of the year. Though they'll still have Warhammer to take care of, and the Jurassic and Planet franchises may also call for new content.
We'll see how all that will turn out. But we know by now that, at this point, we can judge Frontier products only by their release quality, nothing else.
In that situation, keeping communcations to a minimum may not even be the worst strategy.
