Ah, the "do we pay Erdnase" or "get permission for the double lift" arguments.
The double lift has been around for a very, very long time. It is part of our lexicon. It is not proprietary. One need not get permission to perform it or use it.
Lennert Green invented the Angle Separation. Not only did he invent it, he sells it as a manuscript. We KNOW who invented it, and this person makes part of his livelihood by offering his ideas for compensation.
If you want to use the double lift in a trick, there is no problem. But if you want to use Lennert's move, then there is. Now, Lennert may be happy for you to use his move. He may not care. But shouldn't that be HIS decision, not yours. (In truth, this move may have moved into the common lexicon, but that should be Lennert's decision.)
Because when you make it your decision, here's what happens: The people who used to offer their ideas will STOP! In fact, many already have. They see people use their ideas, republish them without credit or permission, and figure - why should I help these thieves.
Two of magic's most inventive geniuses walked away from sharing their magic for this very reason. One now has nothing to do with magic, the other only shows a very few close friends.
Because of our attitude of entitlement, people have lost out.
Now, what about paying Erdnase? Well, Erdnase is a book that is out of print. The creator does not make money of the sales of that book (and after he sold his stock to Drake, there is a question if he ever did). But, Paul Harris makes money off of his books. Daniel Garcia and Dan and Dave make money off of their DVDs. If I wanted to use a Paul Harris trick, I should do the right thing and buy a copy of the book/DVD to compensate him for his work. Do you think it's right to take ideas from people you admire and not compensate them for them? After all, if they meant for their ideas to be "free" why did they sell them in the first place?
Now, what if I don't pay Paul for his trick. Maybe he'll start to feel the way the other two gentlemen I mentioned did and decide it's not worth it. Why take the time out of your life to release something you may have spent years on, and not get anything in return for it? If your favorite creators stopped sharing, how much better off will you be.
As to this idea that you have to have access to free material for the art to grow - that's nonsense.
At this time in history there is more free sharing of material than ever. Has innovation improved?
Not at all.
There are more derivative half baked ideas on the market than at any time in history. Sure, there are greater numbers of items, but the quality overall has diminished.
Now, I am not saying magicians shouldn't brainstorm or share ideas or even resources. But there is a difference between saying to your buddy, "Hey, I just found a cool trick I think you might like" and "Hey, why don't we go in together, each buy one of these books, and copy them."
And ultimately, it comes down to what you think is right. If I find a trick and I know I am going to get value out of it - I pay for it. Even if it's in an out of print book, I track it down. I know the creator gets nothing for that, but at least I spent some time and energy in honor of the person who was kind enough to give me a gift.
If you don't care...you don't care.
But trust me, it DOES impact your world, and a lot of great material will never be shown on DVD or at a convention or sold in a book just because of the attitudes shown here.
Do what you will, but remember - it matters.

p.s. Thrall, this is not about EXPOSURE. As long as you think that, you are missing the point. It is about intellectual property and respect for creators.
