I see someone really gulped down that Apple kool-aid.

Your life is absolutely untouched by having other store options. And privacy is maintained by the granularity of the permissions, the manual review process is generally a joke and it changes like the weather.

If your social network is only available on a store not respecting your privacy and it's normalized people install stuff from there it's a loss for you since you don't have the option for the app that's compliant with Apple's privacy rules. Either you give in to more privacy violations or you give up being able to speak to part of your social network easily.
