Forced ads = uninstall. The ability to purchase no ads is not an excuse. Incentivized ads are fine. Having the option to purchase no ads is fine. When I am forced to watch ADs or forced to buy badly monetized games, I uninstall immediately. Either charge to buy the game, or keep it optional. Pretending your game is free while injecting it with grossly abused monetization is lazy. Make a good game and people will gladly support it.
