CON ARTIST OR FREE MARKET ECONOMY?

I've been reading a lot about Joel Osteen being a "con artist."

Now I get that his biblical history is a little weak but "con artist?"

He says stuff that makes people happy or content or....whatever. They send him money.  He buys an eleven million dollar house.

Does he have a good gig?  Yeah, but I fail to see the con.  I see a value for value transaction.
