With this explanation, the author explains the diminishing returns by the fact that their value decreases ("impact"). I disagree: returns diminish because their cost increases. Assuming a thing can generate 100% of some value, the range 0-20% generates as much value as the range 80%-100%, but the latter range is more costly than the first range.

The return of centering the buttons is significant, because if they're not centered then the product will look unprofessionnal, which is not good for business. It just happens than the cost of centering them is high, in this case as high as setting up the REST service in a first place.

The return of having your company survive is extremetely high. It just happens that this cannot be done with the first few dozens employees but with hundreds more, which is of course way more expensive.
