"Sidwyn is an experienced trainer who teaches iOS development to numerous individuals, professionals and companies. "
"Experienced trainer".
Not "badass developer that has gotten rich building apps."
The site doesn't represent in any way that Sid will teach you how to write an app that will make you rich. It's totally focused on learning to program. Home page, everything. (Unlike the get rich real estate seminars that essentially represent that the person running the seminar has made a fortune and you can learn their secrets. In that case your comment is obviously valid.)
Knowing how to program and knowing how to evaluate the market and write a program that can make money are two different things.
As only one example, would you rather learn about programming from Joel Spolsky or from Mark Zuckerberg? (And I'm specifically saying programming not what Zuckerberg could offer that isn't related to programming..)
Edit: "evaluate the market and write a program that can make money" I'm not saying this is what Zuckerberg did by the way.
