Starting with a clarification, because there are two distinct issues that are being discussed here, and they are blurring. The discussion that originally prompted my to contribute here was about whether custom content was owned by EA, or by the creator. This issue is no more relevant to paysites than any other sites. The issue does affect me in a way, because it makes the difference between me doing something for myself because I enjoy it, and me doing unpaid labor for EA. (Although it doesn't really cause me concern, if they want my stuff they can have it. They've already put rugs in the game and seasons will have harvestable crops, so meh...)
I think that it is fair bet that even if it were taken to court, EA would support the position that custom content is owned by the CC creator, simply because claiming otherwise would leave it open to a ratings nightmare given all the adult CC out there. Of course, that's not really a satisfactory legal argument, which is why I did my research into copyright as it applies to derivative works in the first place. And I still believe those findings hold true.
When it comes to paysites, my original statement made it clear that if one can prove that someone is making
profit from Sims content, and one can also prove that no agreement exists between the creator and EA, then that is proof that the work is not authorized and so it can be treated it as if it were any other EA content. The only significant point there against your actions here is that the burden of proof is on the person redistributing, not the person creating.
(As a distantly related side note to this, EA made a modification to the EULA for the
original Sims tools and materials after a similar discussion to this, specifically called out recouping costs associated with a website as legitimate and permissable. Not really relevant here, as it was for a different game, just an interesting tid-bit.)
The objections I made to the behaviour of members of this site that Jesse was referring to were not based on the legality of the behaviour (and I said as much in the addendum to it) but on the behaviour itself. As I said previously, if I make an agreement with someone then I will do what I can to make sure that I do not breach that agreement. If the other participant is legally questionable, then I will try not to enter an agreement with them. If I
do still enter an agreement though, then I am responsible for keeping my end of it. If a creator has set out an agreement for downloading, and you download that content, then it is your responsibility to keep your word. This is the biggest thing that I find objectionable about the group's methods, and any amount of "but they're bad" won't restore that lost integrity.
Well, that, the bullying that goes on, and the fact that some of your number are doing this specifically to break down an uneasy peace in the community. But those individuals never claimed to be doing otherwise, so pointing it out is hardly worth it. These are all slights to my personal ethics though, nothing that could really be argued from a legal standpoint.
As for games allowing modders to relicense (and/or charge for) custom content, you are right in that very few games have done so in the past. However, at least
one game (which I personally can't stand) is doing it now, and doing so extremely successfully. I think that as skills for custom content creation fall further from the techy few and further into the hands of the general community, the more potential such a system has. But that's just speculation.

Any creation placed into the .package is a derivative of EA's creations, EA's code. If it's a recolor, it sits on EA's meshes. If it's a new mesh, it's still in EA's personal format.
And that's why it's a
derivative, which doesn't preclude a creator's copyright on the new content. And while it does preclude making a profit from it, I've already covered that several times over.
If it's providing someone's sole income, or is going towards paying other people to make files, it's no longer a bandwidth "donation."
Absolutely. Never disagreed on that front. Can you prove the profit legally?
Arguing back and forth within the community isn't ever going to do shit.
Well duh... But then what exactly is the point of membership in this forum? Or of actively starting threads to provoke such arguments?
As opposed to being labeled uncool and unintelligent for not agreeing with Delphy?
Point taken. Although for clarity's sake, I read "cool" as "cool headed" rather than the American high-schoolism of "popular". Just one of those cultural things I guess.
