I certainly don't think the product is dead. They just hired a bunch of developers last year or so after 2.2 major was released. Why would they hire all these folks and then do nothing? Ok, they built cloud, and maybe that's why they were hired?
I'm also sure they are busy with the fall out of cloud support/updates/maintaining a brand new product line. Lots of unknowns pop up and need immediate action in a new product. Meanwhile, the cash cow - xf licenses - funds the activities for the growth channel.
From a business perspective, they are doing everything right to maintain and grow the business.
As customers, we will always want more. And then, people will complain that it's bloated

But we need to realize that there's not a lot left to build. There's always 1-off features that a handful of people want, but a core feature is often challenging to validate cross-customer need.
It is a bit worrying that Mike never posts, Kier shows up once a quarter(with some good content!), Chris is here less it seems, Jeremey only posts in the developer forum once in a while, and Brogan mostly just posts ducks lately, but that doesn't mean they aren't working on the product. In fact, it may hint that they are all heads down on it instead of putting in extra effort on the boards.
Either way, we'll find out soon enough. In the meantime, enjoy your board and focus on your community.
