There are only really two significant questions here.

1 are turbine making more money from selling these potions than they are losing from those annoyed enough by their sale that they stop spending / playing.

2 are more people having fun from the potions being available and used than are not having fun because of the use of the potions.


Now since the potions are still available on the store and based on previous Dev posts, I'm pretty sure they have solid metrics on what goes on in game I would suggest the first question is answered by the first option.

Based on this thread is day that the second question is also answered by the first option, though that's a bigger assumption.
