Considering how many people are currently playing the game, it seems they are pleased enough overall. If they weren't, they would quit playing.
Not everyone is going to get upset over bots when most players only see a minimal negative impact on their game experience. It's mainly those trying to get rich by selling on the marketboard who get upset because the bots are now direct competition. Few of them are so upset they're bothering to quit the game over it, or at least not enough to get SE to take a stronger stance.
