I can access my friends contact info (including email addresses and phone numbers) as I like, within FB's platform. FB just restricts me from accessing that once I;m not longer connected to it. Indeed, you're right - that's the argument - but I suspect it's merely used as a justification to FB's commercial benefit.

Yes, but the question was about downloading what you put in, not what other people put in that you happen to have access to.

I put in email addresses. I can't get them out.
