Either way, I'm willing to give it some time. If they actually do lead to enough revenue to hire more staff and jumpstart the game, I'm all for it. They will need to provide us with updates though. 3 months of these ads with no evidence the game is progressing towards improvements will not be pleasing.
FWIW, I barely notice them on my PC. It's the ad popping up at the bottom of my mobile screen that's really annoying.
