> Adding features just because is not a useful way to spend anyone's time, doubly so in a business context.

You could make this statement about anything. "Building a new hospital wing just because is not a useful way to spend anyone's time", "Adding an extra drive-thru lane just because is not a useful way to spend anyone's time". The point is that it's not "just because", it's because you believe it can grow your revenue.

On the other hand, if you don't believe that, then don't invest. Nobody's saying you have to. If you think my comment is saying that, you've misread it.
