Agreed, but being that the vendors(for different software platforms) are purchasing those slots to advertise their products more broadly, it wouldn't make much sense. Plus it works both ways. Personally, it doesn't bother me, and I'm sure it doesn't bother the content makers just as long as their product ad is reaching their targeted software users. Now if Daz content ads were only being displayed in Poser content sections or vise-versa, then it would be a problem.
