This conversation has one foot in design, another in engineering and yet a third in marketing.
Simplicity is about the usage of the product. It effects the user. Complexity as present here, the 'amount' of features is about the purchaser. These may or may not be the same person, but they definitely have different perspectives and the criteria for purchase and usage are different.
These are very different contexts. The reason that users buy a particular product is for the benefits (pardon my marketing hat).
