Do you have a source for "Facebook associates IP's with Facebook accounts, then tracks Chromecast requests from those IP addresses"

That's not really possible for a webpage or mobile app to do (at least not on iOS, anything goes on Android I guess).

I wish I could find the article. I read it about a year ago. It was a pretty lengthy write up on Facebook's offline tracking habits... just disregard until I can prove it!
