So I am not really following what this is about, but it seems like Facebook wanted to know what information Snapchat and others were collecting from users.

So with the users permission (for a testing group), they created something to be installed along side so that they could see what data was actually being collected by third parties.

I don't understand the issue, If I as a user want to monitor what is being sent about me, I should have the right to do so. If I then want to send that information to some other company, in exchange for money (or whatever) that's my choice.

The headline seems disingenuous.
