Popularity is what you get if you have a good PR department. Good design often has little or nothing to do with it.You are still mixing up logic.
Popularity is not the design goal. Popularity is what you get if you follow good design principles.
If the simple = popular equation actually held true, everybody would be using Apple products.For your information it is "KISS => highest level of user acceptance and interaction". As you can read in the article I linked to.
And "highest level of user acceptance and interaction => easier time of gaining popularity".
But that's not the case; as (for computers and phones, anyway) Apple have for ages been stuck at about a 10-15% market share.
And why is that? Monetary cost aside, it's because that simplicity comes at another price: a loss of control over how the product functions. The user has to bend to suit the product (and accept being locked in a closed ecosystem), rather than being able to make the product adapt to the user's needs (sometimes via 3rd-party add-ons).
The same applies to RPG design. A rule-set made up of numerous discrete subsystems is far easier for a DM to kitbash into what she wants it to be than is a rule-set that hinges on just one or two unified mechanics; because a discrete subsystem can be changed (or, sometimes, eliminated) without affecting too much of the rest of the game while changing a unified mechanic affects the whole game rather than just what you want it to affect.
