I mean, the permissions do have reasonable explanations - using your contact list to 'find friends'- for instance, or writing to your call log because they're integrating VoIP calling (I assume). The wording is just a generic Android permission explanation and comes with any app which requests that permission. If you really can't cope with it, there are apps like Tinfoil which allow you to still use facebook without that added functionality and permission requirement.

A good improvement for Android would be the ability to only request permission when it's required for some key permissions (the way iOS does with contacts (I think)). Enable SMS integration in messages? Android pops up a thing saying 'Facebook wants to be able to read your SMS and MMS messages. Cool?'. UAC for Android.
