A few comments
Yes, Apple's App policy sucks and it shuts down apps at a whim while keeping apps like (inject personal beliefs here) Planned Parenthood alive (ironic use of words). You will see smoking apps still hanging around and that is generally because they have not been updated. Once a new version is released then they will kill the app, but they seem to still allow fixes.
But, I don't let one app make the decision for choosing a phone.
