Re: Just say no
> Its major advantages are no central database of identifiable information and clean iOS/android interaction.
Big assumptions there:
1) It's okay for Apple and Google to limit what others can do with their platform - and actively take measures to prevent rooting...
2) Whilst the approach places different requirements on the central/distributed DB, you are assuming that their approaches don't upload any of: phone number, Google unique device id., icloud/google account details, usage of other app's etc...
3) In using an iPhone/Android you've already given Apple and Google permission to upload usage information to them, so no legal recourse...
