If the problem is the money to keep up the servers I am more than sure if you made a funding campaign you will find funds even from retired players that would easily come back if they knew the game became enjoyable again.
off topic: Im working in data-analytics. On occasion we have clients willing to know what they can do to attract more customers. So, we do the analytics and present them the exact solution, lets say A.. There is a certain type of clients who react in the following way: "Oh, thats interesting, but we dont have budget to implement solution A. Can you please "re-calculate" your analytics so it would suggest B? We would like to do B. We have budget for B. We want to implement B".
Sometimes, they care about the problems only on paper. They just want to make nice presentation for their bosses to show them, that they are doing a perfect job. Because they are doing shitty job...
My guess is, this could be the same story in Munich as well. We all know what the problem is and what the solution should be. Except of TK-Management Team. They are probably celebrating the growing number of new "accounts".
