A lot of players have quit due to afk farming and similar issues within the game that hasn’t had any or lack of attention from the staff.
Sure a notable portion of players may quit when afk farming would be made impossible without the use of macros or botting.
However when and if they will be able to bring new players or old players into the game and the population would rise it would be very beneficial for the game to not have afk farming system in the game present to keep these players and not let the population drop again. Of course there’s lots of other factors as well but I believe this could be the final straw to many as it is extremely discouraging unless you do it yourself. As you said many players see this as a moral thing so they don’t want to do it under any circumstances.
Of course there isn’t too much benefit if IMC isn’t able to bring in more players but if they don’t the game will die anyways. In the longer run this change could definitely help with the reduce of player base, I’m sure the gain will outgrow the initial player loss when this change would happen if given some time.
