Then you are wrong. Market places aren’t static. Just because someone has heard of candy crush, doesn’t mean they have played it. Just because you have heard of candy crush, doesn’t mean that everyone has.
You have placed candy crush in the “inept set” ie you have heard of it and maybe even played it but have decided that it isn’t for you.
Some people have never heard of it and it’s in the “inert set” for them. They have had no reaction to previous marketing.
Then there are people that have played it but stopped for some reason. Reactivating these accounts is the easiest money to make because they don’t need to be guided to the store. They already know where it is. They probably even already spend money on other similar games.
