That's only true if you assume that 99% of Wix users are Wix users because they correctly picked a simple tool for a simple need. But that's a tautology. The problem I describe arises when someone looks at Wix, gets the impression that it is a tool that magically makes it trivial to create a great website, and then assumes they can get the yacht they have in mind for the price of a used sailboat. Most of the work involved with creating a good website isn't technology, but rather strategy, writing, design, and other things where Wix won't help you or even gets in the way.
