Re: Every of my contacts has a limited license to use my number to call me...
No, in some jurisdiction it's exactly how it works - feel free to read privacy laws. They are personal data and you can use them for the purpose they were given to you only. Someone I gave my number can call me, but can't give my number to a third party without my permission - which, by the way, has always been the correct and polite way to handle someone else data.
Only data in *public* records (i.e. public phonebooks) may be used without explicit permissions. And while individuals may be exempt from many legal procedures in handling third party data, they are usually not exempt from the need to protect them, and the associated liability.
Facebook & C. would like you to think you lose ownership of data you give someone for specific use (look also how FB, Google & C would like to cripple copyright....), becuase their whole business is built on someone else data. Just the law in many countries say something else.
Facebook slurping, like Google's and Microsoft's, is on a very dangerous line. "Safe harbour" has been already struck down because it didn't comply with EU personal data protection rules. Let's wait for a Schrems with enough time to look into those data slurping capabilities, including data of third parties who never signed any agreement with FB or the like to use their data.
