Does all that copyright crap even matter?
As long as you say, "It's not mine, it's theirs and I don't own any part of it.", then it shouldn't matter.
themountainclimber touched on this, but let me try to explain their position on "that copyright crap". Fremanltle has a large investment in The Price is Right, speaking strictly monetarily. It is their IP (intellectual property). If you went out and built a house to rent, you would be entitled to the rent, not your neighbor, right? The same principle applies... they invest in their brand, and they are entitled to make all the money that can be made from it, and no one else. You wouldn't let your neighbor rent out the basement of your brand new house, right?
Even if Jon or others make no money on their "fan creations" they are still riding the coattails of Fremantle's success... and if someone enjoys Jon's game, they just might not buy Ludia's, or play the facebook game, or what have you. Fremantle has every right to both request and require the stoppage of anything that prevents them (or could prevent them) from fully capitalizing on their investment... just like you could throw your neighbor's tenants out of your basement without any problem - they're trespassers.
While some companies allow fans to create and publish their tribute work as long as they do not profit from it, others do not. Fremantle falls into the latter category, and that's just that.
Maybe one day in the future, Freemantle will get a better director or copyright laws won't be so strict anymore.
Fremantle would do well to embrace their fans, I agree. Paramount does this with the Star Trek franchise, and there are some great fan created episodes, movies, and stories which are published for free viewing. As for copyright laws becoming less stringent, they won't, and shouldn't. Copyright laws protect content creators, which is a good thing.
