My counter-argument basically boils down to two broad points. When we're talking about games like CP, I can understand your point. I personally find it distasteful, I concede it grudgingly, but I get it. As a side note, I've said many times that I would gladly support CP if things were different, because I think that game is more than deserving of having all the work that's been put into it compensated for.
The thing that actually bothers me is that every dev would have to be questioned in order to make things fair. In some cases, there are devs whose games are in the database but can't be reached. Either they've disappeared, they've passed away, etc. What would you do in those cases? I'm thinking specifically of Kitchens Inc games at this moment. Everyone knows that there were many sounds he used which were Simpsons quotes and things like that. The right thing in that case would be to blacklist those games, but since he's no longer here to correct the problem, even if he wanted to, are you comfortable doing that? There are many older games which could potentially fall into this category, and we just don't know how the sounds used were obtained. In an all or nothing approach, we'd have to get rid of all of them to err on the side of caution, whether the sounds were obtained legally or not.
My second point is that, even if we were to give games that are older than a certain date a pass, or exclude devs who cannot or will not respond to inquiries, we've still got the problem of proving that Game X uses sounds that were legally obtained. These days, almost everyone encrypts their sounds, and for good reason. Would you feel comfortable prying into every single game and examining each and every sound to try and figure out where they all came from? The key word there is try, because even then, I think the lines can get blurry. To use an example, let's take STW. I'm not picking on Sam specifically, it's just one of the largest games this community still plays, thus why I'm calling it out. How do we know where he got those sounds? Even if you questioned him, he could say he received a paid sound library as a gift. How would we know whether that was true or not? Again, I don't play that game, I have no clue what sounds it uses or if it even does use paid libraries, I'm just going on what my impression of the game's quality is.
To get back to the sound libraries example, if someone did purchase sounds which could be used as long as they were credited, would they then have to send each game they make to a board of judges, for lack of a better term, to be poured over and scrutinized before it could be posted to the New Releases room? Would one of the requirements be that they had to attach the receipt for their purchase of said libraries in order to be believed? What if, as I said, the sound library was purchased by someone else, so they wouldn't have the receipt? Does that disqualify them, because anyone could lie about that so easily? Look, I get it. I want all the stolen code and bickering to die in a fire as much as the rest of you, and a vetting process would be one way to kill two birds with one stone, but I don't think this is the way.
So, what I mean by driving the community away has very little to do with games whose sounds are obviously ripped from other sources. We can agree to disagree about how much harm such things actually cause. What I'm getting at here is the vetting process. It's Apple all over again, minus the exorbitant fees, of course, and I don't think a lot of people are going to take that lying down. Besides, and this is most important of all, whether your intent is to start a witch hunt or not, you, the moderators, won't have to facilitate that process. There's a certain subset of the community who will do that for you with great gusto and pleasure, and we all know it. There's no need to sugarcoat it, because once the kids get their toys taken away, so to speak, they're going to pounce on something else. Only this time, it won't be "clone clone clone", it will be, "Little Jimmy used a bad sound, I'm gonna tell on him!" Do we really need more of that? I think not. Most of us are growing extremely tired of the clone drama already, I think this just might be the straw that breaks the camel's back.
Finally, I could be wrong about this, but making the Movie Vault a paid service won't make it legal. Have you ever heard of Megaupload? It had a paid tier of members, just as many file sharing services do. But, because it was hosting illegal material, it was taken down, and everyone who paid for it lost their money. At its core, the Movie Vault is a file sharing service, the same as Sendspace or Dropbox or what have you. Just because it specializes in a certain type of content doesn't mean that charging money for it will magically make it all better.
The glass is neither half empty nor half full. It's just holding half the amount it can potentially hold.
