I don't know why they changed the rules, I do have a feeling how it could have happened though. They definitely could have gone about it another way. I believe the problem comes from the fact that downloads can be restricted by age and content, previews cannot. So if you've got a 5 year old who isn't allowed to download adult apps if they go looking for a Wubble app, wobbling bikinis might be one of the results shown. For some conservative parents this can cause a problem. For most programmers an extra line of SQL could have fixed this so I don't know why apple is using this ass backwards approach.
