A serious question: Can someone explain to me why this is an issue?

Facebook chats are stored on the servers of a company that I have no control over, that is not funded by me, and that has repeatedly demonstrated a commitment to getting people to reveal things about themselves.

And meanwhile the U.S. government is listening to our phone calls.

Are Facebook chats read by the U.S. government? Of course they are -- even if the claims in this article are completely false.

So, again, why is this an issue?
