I think the OP rightfully addresses a deeper issue at stake here - "I have no vested interest in the outcomes of any of the projects and I wish them best of luck." Or perhaps more aptly put - stop trying to cater to these people, it's a waste of your time.
The world is full of people thinking that what people like Gates, Zuckerberg, etc. have accomplished is both simple and repeatable.
Ever build an app for yourself? Did you wireframe it? I bet you didn't.
When you're developing something to solve a problem you could never even imagine having, say wardrobe management software for the wife of a senior politician you're probably going to need those wireframes.
Totally agree, but it's so rare to find a client-agency relationship like that in the web dev space.

Yes, I have built an app for myself. I've definitely wireframed it. I usually go through a crapload of wireframes, HTML mockups, etc. It's incredibly difficult (for me) to just develop without at least a starting point either written or in my mind.
