The population is decreasing because of promises made that have not been kept, not much has changed. On project Earth (the private server that was up for a while, when kk decided to give everyone the server files back in patch 16X) , there was about triple the work done to improve performance, and the quality of the game, in about a week or so. Yes, they are trying, but obviously if some outsider can do more work in a week then they can do in what a year? Maybe there is something to consider with who you let work on it..
Long story short, stuff has been promised to people, it is not being done, and that is why populations are dropping back to terra numbers.
