I think it's just a precautionary step after the whole Facebook debacle, FB issues an email address to every user and they were tricking people into sending emails to petition for their service with a click and then sending a notification to all their friends when a person does that making it look like a good thing. What made it even more iffy was that it would've been free on select few services and they planned to include a couple other companies later, it took a lot of convincing and explaining by a lot of concerned people. It was a scary time and no one wants to go through all of that again for whatever reason.
