Apple? iPhone, stealing your data and selling it to Facebook?

I have an iPhone 6. I don't have a Facebook. No Facebook app or login has ever been used on my device. 

Enter exhibit A; 

Notice the very bottom item, Facebook sharing. 6.4kb. This tiny amount of data doesn't look like much but it is. 6.4kb is enough space for a large amount of very sensitive information that I would never agree to share with the shit heads over at Facebook. 

I noticed traffic over my network to a Facebook linked server and have been hunting for the source for a day or so. I actually stumbled onto it. I never thought my trusted iPhone with all of its complex settings and permissions would be the cause. 

I will be calling apple and I'm sure getting the brush off when I ask those technodouhes what the fuck. I might even record the call for quality purposes.
