Well, it's pretty frightening that you're asking for such massive, wide-scale permissions.
I understand that people are permission-clicky-happy nowadays, so it's probably something that won't even remotely affect your growth - it's just a shock to see new, tech-friendly services going with permission-grabs (even if it is, as you say, to allow for better UX)
I can't imagine why anyone would want to give up such massive access, and potentially commercially sensitive info (that they possibly don't own), but I definitely wish you all the best with this
