They made an (anecdotal) video by promising a free cup of coffee in exchange for your contact list on your phone:

My wife has an Android phone, I have an iPhone. Recently, I wanted to install some app on her phone and it is still beyond my understanding, why Google still doesn't allow to deny certain permissions. It's all or nothing.
And no, a fucking video editor shouldn't require access to my contacts, my browsing history and the accounts on my phone.
Android imho is unusable until they let me deny certain permissions, because often, the "best" apps ask for basically everything.
Android isn't the problem. Google is the problem.
[edit] As in, you can restrict access to things like location, contacts, calendar etc.
Would be great to make one similar combining the two concepts in regards to sharing phone data.
'Please plug in your phone here, we need to get some data from it'
'Huh?'
