From what I know and have seen, both in OC and here, there seem to be a few misconceptions about what OC is doing.
First, it's not tracking you at all. However, it is doing more than a Flash banner ad on a web site.
A web site ad does not have the same access to your computer that OC has. OC has several offers available and they don't offer you what you already have, so, the logic is something like this:
OfferList = { ...big list of offers ordered by profitability... };
foreach (item in OfferList)
{
if (item.IsNotInstalled)
{
OpenCandy.MakeOfferToUser(item);
OpenCandy.OsLanguageCountry(); // Log OS, language and country as aggregates
return;
}
}
There, item.IsNotInstalled checks to see if the item exists on the computer by checking the registry. In a way, that is more power than a normal ad. In another way, it's about equivalent.
Anyways, I don't have absolute knowledge of what is going on, but from what I can tell, that's it or at least pretty darn close.
I have not seen the advertiser SDK, so I don't know exactly what goes on there, but my guess is that there is something in it that informs OC if the offered software has been subsequently run. That is the part that ensures that the offered software is genuinely wanted by the user, which then tells OC to pay the original software author (like me). However, I am not certain. Just guessing there.
We trust software all the time. Some people even trust cracks and warez. (Yikes...) If there were something dirty going on, it would be much easier to simply not use OC and do all the dirty stuff in the software instead. But there isn't. It's pretty simple. It presents an "ad" during installation in the same way that a web site puts ads on its pages. The difference is that you're not being tracked with OC, but when you visit virtually any web page, you ARE being tracked by Double-Click or Google or someone. Google keeps PERSONAL track of you even. They use personally identifying information thanks to you having signed up at Youtube or Gmail or some other Google service. So when you visit
www.acme.com, the ads are very specific to that site and YOU.
There are other privacy concerns out there that are much much more serious. But really, people just don't care. They are used to them now. This is just a slightly different way to serve up an ad/offer.
Truthfully, in an installer is PRIME space for it because you have the person's dedicated attention. They aren't distracted by anything else. (Which is the same motivation for why I used a full page back-splash for the Photo Resizer installer --- people aren't distracted then and can pay attention to the installer -- it targets people that are not tech-savvy.)
Anyways, I kind of hope that helps some with tracking and whatnot.
