I agree, but then all you'd need to grant is a non-exclusive right to display and redistribute the user submission as is. Without being familiar with US laws (only with European law), I see little reason to authorize them to use all proprietary rights, which would include selling, altering the code, copying the code, merging addons, releasing them with a new name (or a different license), etc. - and I'm slightly unsure how this complies with the various licenses addons use (GPL,...).
Any addon that's e.g. using a "Attribution-Noncommercial-No Derivative Works" license (e.g. from CreativeCommons) can not be uploaded to Curse under these Terms of Usage.
You don't grant them all those rights.
"authorize Curse to use all patent, trademark, trade secret, copyright or other proprietary rights in and to any and all User Submissions to enable inclusion and use of the User Submissions in the manner contemplated by the Website and these Terms of Service"
You only allow them to use your addon for a specific task, which is hosting, redistributing, and advertising on the Curse Main Page.
Well obviously you need to grant curse the right to redistribute your work, or them hosting your addons would be illegal? :)
I'm not a lawyer, but i had my fair share of law at university, so i can try to clarify that a bit
and authorize Curse to use all patent, trademark, trade secret, copyright or other proprietary rights in and to any and all User Submissions to enable inclusion and use of the User Submissions in the manner contemplated by the Website and these Terms of Service
This part authorizes Curse to include the "User Submissions" in their website, but only for the specific manner already described in the terms of services - so essentially, you just allow them to host and redistribute your addon.
"In connection with User Submissions, you further agree that you will not: (i) submit material that is copyrighted, protected by trade secret or otherwise subject to third party proprietary rights, including privacy and publicity rights, unless you are the owner of such rights or have permission from their rightful owner to post the material and to grant Curse all of the license rights granted herein;"
This second part only makes sure that you actually own all the rights specified above that you are granting to Curse now.
I'm not sure whats meant with the confidentiality in your first quote, but my guess would be, that they are just securing themself against someone claiming that they posted a unreleased ("confidential") version of your addon.
If you search the US WoW Forums on this topic, there have been a lot of discussions about the new ToS/ToU of Curse (some while ago, when the new version was posted), and in return both had been relaxed to fit the needs of the Community, and the community agreed, that it was acceptable now.
Like Mikk already pointed out, what they get is a possible increase in user-base.
A lot of addons on WoWAce are hosted on no release site at all, mostly because the authors are too lazy or never even considered it. Now with the new WoWAce, its one click to release your addon to Curse.com.
So their Goal is, to get more addons to their page, which means more users looking at their ads, and even some people paying for "Premium". Whats the best way to sustain that flow of addons to curse? Of course, keep the developers happy, and offer features here on WoWAce and on CurseForge that are not available elsewhere to attract more devs.
Just to make that clear, i'm in no way associated with Curse, nor are Mikk and Ammo. The second i realize that Curse will be doing something "bad" to the Community, i'll leave with my addons, and i won't be alone. But personally, i do not see that happen.
Kaelten, curse.com makes it pretty difficult to find out who it's owned by. Yeah, "Curse Inc." and Hubert Thieblot (who seems to have moved from Neuilly sur Seine to Huntsville recently). But who is Curse Inc. owned by? As I live in Europe I know how to find out who european companies are owned by, but I don't know how to get this information for US companies.
In any case, it's a company with business interests (which is nothing bad), but the problem is that wowace.com is/was a very open community with the spirit of an open source project lots of people were contributing too. And changing wowace from a non profit community to a business website is a major change. I'm fine with you now being an employee of curse (so I heard, and ckk seems to have been hired as well), but I'm really unhappy to see the upcoming changes to wowace.com - as I have no interest in contributing any kind of content (via community support or addons) to a company that's making their money with this content.
I'm fearing that many developers will be gone soon, for one reason or the other. And that's the end of wowace as we know it.
WoWAce will in no way change to a business website. All addons hosted here will still be freely available to anyone, you just will not get a mass updater due to bandwidth concerns.
All we actually have to do with Curse it the possibility to directly push releases from WoWAce to Curse. Me and Kaelten even discussed the possibility to add more release pages to that list later on - but all in due time.
No-one will have to pay to get his addons, and no-one will have to pay to host addons here. Any Dev will still be free to do whatever he wants - as long as the principles we established for our community are kept in mind.
The only "real" change is that WAU will cease to exist, because it was no longer maintainable with its excessive use of bandwidth, and i perfectly understand that Curse was no longer willing to pay those bandwidth bills.
We tried running Ads, we tried accepting donations, but as it is with Open-Source, people go insane if you add ads to fund yourself, and donating is a word not in their dictionary. We even considered running a "Premium" version of WAU ourselves, but that was out of our scope at the time. So now, after 2 years of trying, we shut down WAU - or rather, Curse shut-down WAU, because they payed for it.
Curse will still be paying the hosting bills for WoWAce, and we should be thankful for it.
Now we can offer a lot new and awesome features to the addon developers, and its all still for free. WoWAce always was and always will be a community from the developers for the developers - and I'm pretty sure Kaelten will make sure it stays that way, and so will I.
Personally, i won't miss WAU and its excessive updating of Alpha versions. It caused more harm then good, if you ask me. Authors now just need to learn to push their releases to Curse, to WoWI, or to whatever page they prefer - like it should've always been.
Obviously we cannot stop you from leaving, but we're trying to do all we can to resolve the issues that might arise. If you have any specific concerns at all, don't hesitate to bring them up with us.
