I always had a struggle with MVP approach when it comes to things like these. You build a minimum viable (non-accessible, since, as the article states, that's only 15% of the population, a common ignoreable percentage for MVP) product, but then never get around to fixing it. It's the same thing as with untested code, you need to find a point where you say we don't allow inaccessible stuff anymore. But like with tests, old stuff never gets fixed until it's abandoned. How do people fix this?
