currently monstermarket is the most used market. and obviously not because of the additional features but because of the cashback. how much cashback do you think the cashback markets will be able to pay after the change? obviously their business model will be destroyed. you can ask e.g. reazuliqbal the operator of monstermarket or read what he wrote today in discord, or just see if he voted against it if you don't believe me.
he said something different than i did and also worded it much nicer. but he was obviously not enthusiastic ;)

seeing that most players prefer the cashback model to the add-on features. how can you go there and damage the cashback model and promote the add-on model? there's something wrong here i don't need to explain, is there?

and personally it hits me insofar that they want to take away my choice between peakmonster and cashback. and of course 1% more fees ;)
