While I understand the frustration at the changes and the feeling that nothing is happening about it, boycotting spending isn’t the best way to go about things. It would be more likely to slow down any fixes as more things need to get juggled with less cash, and there would be no connection between the lesser spending and the AI issues. (There are other issues players have with the game at the moment as well)
On top of all this, a boycott would be assuming that the devs are not still working to fix this issue, which they are. And making it harder for them to fix the issue you’re boycotting seems a bit counter intuitive.
