It is clear to me that the next three phones we buy will not be windows phone. We just ordered my daughter's iphone from a windows phone and my wife and I are on our second wp device. Our next upgrade will not be a windows phone. We had been looking at a Surface 3, now there is no way. This experience has undermined any trust I had in Microsoft. Microsoft sold me on family safety and the one windows experience, takes my money and then changes a critical feature to have none of the functionality that my family relies on. It must be remembered that the FAQ page appeared several weeks, if not months after the functionality was stripped. The change happened without notice or warning, leaving our children vulnerable. This is not only "less than ideal", it is criminal.
There is a whole thread of equally furious and disappointed individuals at http://answers.microsoft.com/en-us/windows/forum/windows\_other-security/why-is-there-now-a-separate-account-for-each/9ce896b7-e181-45d5-bca1-03610f6cd920?page=9&msgId=4b78aa57-2944-4a56-9ca2-adeefcffafef
