I only see that the printing company would be benefiting with this route (forever and ever and ever). And that card creators lose ownership of their own work. Copyrights are there to protect people from having pirates board their ships! No copyrights means that
anyone will have the privilege of printing the deck, not only the printing company. And then anyone can change and manipulate anything about the artwork itself, and sell that commercially, which would be upsetting.
I genuinely see how there are very good intentions, of volunteering, of sharing with everyone, of not-profiting, but at the same time there is no protection or safety for the deck itself. After it's done, anyone can have their
way with it, and that's the downfall.
A gift to the world, yet the world sees things in money signs.
I think it's fair to allow copyright, since copyright protection starts as soon as the creation (the card) is made, and the idea has taken shape. And I repeat, copyright protection starts as
soon as it's made (you could put a copyright symbol next to your creations, without ever registering). So by not having copyrights, people are actually losing their rights to their own work, which I would find deeply unfair for the participants involved. Not having copyrights means that anyone can take your work, change it around, copy it, and do whatever they please. It's not a good outcome.
I don't really wish that happen to anyone's cards. I might want to participate, but knowing where it might lead, I'm not so sure I would like to. I'm sure this deck has great intentions, but at the same time, it might be a folly if it's not genuinely raised and cared for in the right way. I would like you to basically think a bit more deeply about copyrights, since it doesn't hurt anyone to have protection. Yet it will hurt without it.
