There is truth to that yes, but work in support long enough and you'll find most people wouldn't even take the time to read through the wikipedia documents based solely on the fact of its small font, cluttered look and scrolling documents (up and down scrolling). It is intimidating to most people.
As for the dumbing it down, ever been in a situation where people are using jargon on a subject without you having reference to what that subject is? It can be frustrating fast, and nerve racking as well. Wikipedia has the information and links to get you through it, yes, but its overwelming to the average person, especially with the computer topics. You, me, and most of us on these boards have the patience and understanding to navigate wikipedia with ease. Average Joe gets frustrated or fed-up fast. It will get better as the generations shift (youth become old, old becomes deceased - to be very simplistic), but today wikipedia isn't the grand solution for the whole... tomorrow who knows
