I haven't used FB in a long time and I never used their mobile app, so here's a genuine request: do you have a screenshot or some example of how they gather consent for this?
Thanks. It confirms my empirical experience that most users (of all backgrounds) don't read, those who read don't fully comprehend the information, and those who comprehend it are thrown off by cute illustrations or the urgency of what they want to accomplish in the moment.
Personally, I'd prefer the message to be split in two parts, like so:
------
# Text anyone in your phone
This lets friends find each other on Facebook and helps us create a better experience for everyone.
## Privacy
This will continously upload:
- Info about your contacts like phone numbers and nicknames
- Your call and text history.
------
(I don't think I'd have gotten FB to a half-trillion market cap.)
