I disagree in the case iOS 7 betas. iOS 6 betas spoiled us because they were so solid. iOS 7 betas 1 and 2 were basically garbage as a general release. One of our devs had to figure out how to dial into AT&T to get his voicemail until Beta 3.
Apple's betas are not "Google betas" where they're pretty solid at release and keep the beta monicker until we've learned to ignore it. This round of Betas have definitely been early releases so developers can get a grasp on APIs and UI changes and nothing more.
I think you misunderstand, I do not think any end-users should be running beta iOS releases. It is just obvious from this problem that many are, and Apple needs to deal with the problem.
