I understand what you're saying, but everyone's got to make a living. There's nothing wrong with selling stuff or services.
The nice thing is he gives out SO MUCH knowledge and research free. All that takes a lot of time. His time is valuable and worth something. I wouldn't mind paying for it.
He's helping people for FREE, and what he says is as true as it can be in this ever changing world. So many people in here fabricate facts and tell people to do dangerous things. It's hard to find someone to trust, and I trust him.
Again, I see no problem with selling products or information in here.
