Would it help if I explained to you why a maps app in general would need that information or is this something you are strictly against for one reason or another? Feel free to list the permissions it asks for and I'll be happy to explain.
A different OS would not help you. Even if you went to iOS they ask for the same exact permissions when you use their Maps app except they don't really tell you unless you feel like reading a long-winded Terms of Service agreement (except Contacts. I forgot it actually does have a pop up that says do you want this to have access to contacts or something like that). I'm not familiar with Blackberry's OS, but I'm pretty sure it's the same circumstances.
It all really boils down to understanding what convenience vs. privacy really means. To me, if the company is transparent enough to at least post what they are asking for, then that's fine by me. Making me sift through ToS...is not something I want to spend my day doing. At least Google, in my opinion anyways, has the best approach which is biting them because of privacy advocates.
