Every company has the same reason to be here. Make money (no their meaning is not to satisfy everyone). No they do not prefer something which makes less money, cause it will cost them their company in the future. Both those games have their separate teams.
And about that "arent very interested in the game." Well few weeks ago there was a camp for many content creators made by BI, they even hired few modders there, they do blogs regularly, they are making patches and updates for 10y old game (which you had to pay for ONCE). I dont know buddy. I dont think they dont care. I think they are just not so big to be 24/7 on those forums. Ppl are complaining about the Frostline price, about the Livonia being free, etc. Still company made for profit, and kids are crying cause they do not have enough attention and they have to pay literally for thousands of hours of fun twice.
And about the issues which should not be in 2024 game: Well the engine is pretty old, they for sure are trying, they even fixed few of the most annoying bugs (ADS, etc). I really think they would make it perfect, if the code allowes them to do so. They made this clear many times. Unfortunately, Dayz has extremely complex and old engine which allows for many things you do not even realize in game, but also fixing one thing usualy messes with few other things. So conclusion: It is not they do not feel passion, or they do not want. It simply is extremely hard and to be honest, the game with its flaws is the best it ever was. Lets remember few years earlier, right?
