This is an interesting point, but there's slightly more to it than that. When something is simple and does the job well, it has limitations. The problem is that adding each subsequent feature has a small benefit and a small, but immeasurable cost. Sometimes that cost outweighs the benefit, but knowing that before the fact is very hard, and removing features is almost impossible as people shout disproportionately loudly about losing things.

It's similar to the problem of regulation. Looking at each individual law, it often seems reasonable. It's only when there are 10,000, and everything grinds to a halt, that people realise there's a problem.
