I am concerned about this statement...
"Finally, as a content vendor, I would be concerned that the EULA states I have no copyright on my own creations. Why would I wish to give away my rights by agreeing to the new EULA when the previous EULA does not claim the content of those file formats to be proprietary? And why would I want to restrict my sales only to stores that were Content Paradise participants?"
Where has CL drawn the line as to what can or cannot be copyrighted. Although I am not anywhere near mastering Poser so that I can make some of the neat things offered at this website, I hope one day I'll grow to be able to create things and join everyone else. But if I keep burning the midnight oil, practicing and learning only to reach my goal and find that CL has this EULA that gobbles up the copyright to something I've created, what's it all for. CL should protect it's interest I agree. But, it should also specify in detail what the fine print or lack of really means. If CL is going to go after someone based on some fine detail when their broad brush didn't specify that detail, I think that would be wrong and abusive. Let the folks know what the real deal is. This establishment of terms to address the pirate wackos unfortunately assumes that everyone is going to do something illegal and all must be reigned in check. It's kind of insulting when you are an honest person. CL wants us to trust their EULA, but they don't trust the community of users. So, again, I say, put it in writing and don't be vague and sweep with a broad brush explanation.
