If we were able to take a poll of all the people who play or have played, and created a chart that illustrated how many people play, how many people spend money, and how many people have played long enough to float on only donut farming, we'd likely see what a minority we are. Thousands of people play this game daily. Only a few dozen know to farm donuts. Only a few dozen come to this forum.
The game definitely makes money. There are new players downloading the game and starting from the beginning, EVERY DAY. Each new batch of players includes a percentage that will spend money.
I just read the text you referenced. It sounds to me like just another typical take-down statement after an event ends. Please do not worry needlessly. Please instead, keep calm and tap on. Please.
