Unfortunately Chrome/Android has a terrible approach when asking for permissions. Since they only know the class of permission (instead of what the dev is doing with them), they pop up a scary-sounding warning and hope the user figures things out. On top of desensitizing users to real threats, I can recall many times when I decided against installing an Android/Chrome app because I couldn't/didn't want to figure out how it would impact my system and didn't want to take a risk on some one-person operation.
Amusingly, I never had this issue on iOS because Apple never warns you and as a user I can assume (rightly or wrongly) that all iOS apps are safe. I wonder when Google will catch on because I personally still feel their app marketplace is much more dangerous than Apple's.
