3. License To Use Artist Materials. As and when Artist Materials are
uploaded to the DeviantArt Site(s), Artist grants to DeviantArt a
worldwide, royalty-free, non-exclusive license to do the following
things during the Term:
a) to prepare and encode Artist Materials or any part of them for
digital or analog transmission, manipulation and exhibition in
any format and by any means now known or not yet known or
invented;
b) to display, copy, reproduce, exhibit, publicly perform,
broadcast, rebroadcast, transmit, retransmit, distribute through
any electronic means (including analog and digital) or other
means, and electronically or otherwise publish any or all of
the Artist Materials, including any part of them, and to include
them in compilations for publication, by any and all means and
media now known or not yet known or invented ;
c) to modify, adapt, change or otherwise alter the Artist Materials
(e.g., change the size) and use the Artist Materials as described
in Section 3(b); and ...
The only thing a DeviantArt user can do is to delete their content, shut their account, and leave the site.
The policies only apply for the "Term" in which a user exists and the art exists on the platform.
a) We can re-encode your images, to whatever format
we need to make the website work.
b) We are allowed to display the pictures online.
If something happens and the internet stops existing,
we'll still be allowed to show people pictures where
we go after the web. We are also allowed to display
pictures not only by themselves but also as part of
a gallery. E.g. in search results.
c) We're allowed to resize, convert to grayscale, etc
so that galleries, search results, etc, all work
the way a modern website is expected to.
You need all those rights to be able to operate DeviantArt. You really don't want the licence to become the limiting factor when you implement a new feature on the website, so you need to be quite broad.
Sure, but you those very same terms could also be used to operate something entirely different from deviantart. Was the parent post accusingly pointing fingers or was it just dusting facts?
That Wix scenario doesn't look all that terrible by the way: imagine deviantart pivoting into some kind of racket machine publishing connections between cringeworthy "early works" and the current employers of meanwhile professional graphics artists, now that would be an evil use of the repository.
I'm no lawyer, but it looks like that language grants the DeviantArt corporation rights to use submissions, which they need in order to provide basic search as well as marketing.
It would be a different thing to grant Wix users the right to take someone's work over to their own sites, I speculate that would require an extension or transfer of copy rights in addition to the quoted policy.
I'd wait and see, I'd expect that Wix won't just lay claim to all submissions without asking for permission or remunerating artists who's works are sold.
Notice it says nothing of re-licensing to others. These terms seem to facilitate DeviantArt's (and presumably its owner(s)) ability to show your work to the world on their site. But does not facilitate their sub-licensing your work to others. If I were an artist and loved my DeviantArt account, I'd make sure to hold them to task if my work showed up on a Wix customer's site.
If I understand wix.com's product correctly, those customer sites run on wix.com's servers. So, one could argue that it would be wix.com that shows the images. It would not be clear-cut that this infringes on that license.
I do hope that wix.com will do the right thing, though, and limit this to images that their creators permitted to be reused and/or add a feature where wix customers can negotiate with deviantart users over pricing.
This line is pretty common in ToC's as far as I know (I'm no lawyer). It allows them to show the images on the site and in advertising. Nothing too uncommon, and most of it's needed to make the site work.
"Royalty-free" doesn't mean they can just do what they want. It means they're not going to pay you for the things listed in the license (to which you agreed by hosting on their site.) It doesn't even say "...perpetual license." It's clearly limited to stuff you've put on their systems, while it's on their systems. You remove it, they can't use it.
The policies only apply for the "Term" in which a user exists and the art exists on the platform.
