You can only get so far with a blog post. Have you filed a radar yet? I just did (rdar://9598285). Here's the text you can copy and paste (make sure you mention it's a dupe of 9598285). * Title: Users leave bad reviews for app that don't work on beta OS releases Summary: The point of the prereleases is to give developers time to modify their apps to address any compatibility issues (as well as add new features) before the public release of the operating system. Despite Apple's best intentions at keeping OS betas limited to developers, the fact of the matter remains that average users can and do get their hands on prerelease software. This leads many non-savvy users running applications not meant for the new release and often leave negative reviews on the App Store because the app is incompatible with the new OS. For example, see this blog post: http://mbarclay.net/?p=1317 http://mbarclay.net/?p=1317 One potential solution to this is to disallow app reviews for users running unreleased OSes. Another is to tighten up the developer program so that each subsequent beta release allows more and more devices to receive installs. With the current 100 devices per account right off the bat, there is widespread abuse of access to prerelease software.
