If people want to know how it is done, it is their right to know!
I've invested a very large amount of my resources on learning my skills and knowledge. I am happy to point people in the same direction, but there is absolutely no reason I should give them the knowledge without similar investment, just because they want to know.
If wishes were fishes, we'd all cast nets.
That means his income from that project is cut in half.
Which is a strong de-motivator for releasing products. I know plenty of guys that have amazing stuff that they worked on, performed for a few years, then shelved because releasing it wouldn't be worth it. This is a big reason there's a lot of mediocre junk out there, because the guys who are really creative aren't encouraged to release their good stuff. Better to release the OK stuff and make what they can on that.
To expand on one of RealityOne's points - There's stuff I've managed to get my hands on that if you aren't either extremely lucky, or friends with the right people at the right time, you'll never even hear of. And I'm at the bottom rung of that ladder - I've made some really good contacts, but there's stuff that's only been obliquely referred to around me. There's other stuff you have to learn in person, because only one person is teaching it, and you have to sign a contract to learn it, and they never put it on paper.
I've been pretty clear that I am not worried about exposure, because the method is only a small portion of what makes magic magical. But that doesn't mean I'm going to condone or encourage it. Exposure is a direct display of disrespect to the magic community, and it undermines what magic is supposed to be about. And he's absolutely right - if you start talking about all the stuff you've learned from YouTube, you're going to get a lot of cold shoulders.
As David mentioned, you seem to be on the path of a secret collector. Once you realize what magic is really about, I think your views will actually change.
