The flaw in this argument is that you are measuring across the total population, and totally ignoring that while your overall changes may help some proportion, some parts of it may actively prevent others from using the site at all.

Great for you if all you care about is the money. Not so great if you want to e.g. ensure people with disabilities have a good experience too.
