My point is that this is probably the case for most users; the "more" doesn't mean anything because it's some functionality created by underemployed product managers rather than things that customers actually need/want to pay for. If you have to point out "hey, look here under this 'more' menu", then it's not part of the primary value proposition for the product and not why someone would pick that product. Sure, it might be that it is useful for some subset of users, but that you need to wave people down to show them that value means that it's probably not that valuable.
The amount of businesses whose target audience is “most users” is very small. You might get lucky and be a Microsoft or Apple but almost every other business has a very specific type of customer that they want.
The other thing is that the most popular features aren’t necessarily the most profitable ones.
Dropbox doesn’t make money on the millions of people with free accounts, and they are selling commodity storage for their paid users at thin margins. But a product that can solve business pain in a unique way can command better margins, which is why they are getting into other businesses like document signing rather than just sticking to selling bulk cloud storage.
