While I can understand the sentiment. This is not realistic. The doors do not stay open if they don't make sales. Without infusions of cash its layoff time, shut the doors and thanks for all the fish.
Repeatedly in reddit/youtube now, they have said they have put 50% (60+) of the developers onto core systems. Its getting done... its just not visible to us (but one of the BIG complaints just got a refresh (AI) and is still being improved.)
Plus rewriting/refactoring the code base in 4 million lines of code on an active system and making sure other systems are not impacted is not to be taken lightly. I'm sure at times if feels like your searching for a corner in a round room.
Maybe they need to put a status board up to show progress on the core elements of the game they're working on. Then we could see the sad fact that sometimes something they do breaks something else or they take 2 steps forward 1 step back. Or just don't seem to make progress on something for a while because of integration, complexity, yada yada yada.
Though with the amount of angry complaints that people make I can see why they might really be shy/nervous to do such a thing. Especially because in a way people will try to drive ED's development into their favorite part of the game they want fixed/implemented. Which would be counter productive to what they see as essential to bring the whole together.
