The developers have a goal in mind, a general idea of what they want 2.0 to be. They are open to feedback, sure. Sometimes though, they need to draw a line and say "this is necessary for our goal". That is what Yoshi-P did when he explained why the change is happening.

As supporters of this game, we need to trust that the developers know what they are doing. Some changes need to happen so the dream that is 2.0 can become a reality.
