Facebook: We Put Ad's on Mobile APP!

Ever since version 1.9.1 was built Banners Facebook application,
Last version 2.1 now started to implant advertisements from your posts. (NEWS FEED)
What most do not understand, why? Why do they do this. The obvious answer is "money"
Facebook company goes our privacy! If you think the reason "why I had advertisements for if I do not want them" They know the browser you have AD BLOCKER (most of us), so they planted Application
But the strange thing, "Why should I have Banners that will finish the battery more"

And of course shred vBulletin weighs 20MB after fault that size crazy!! (If they erase this post would consider 16MB) and can be transferred to memory card I

Facebook social question, why are you abusing users? Want people to abandon?
Last time fully disconnect users accounts on the site.

Facebook hope you read this and understand advertising!
