The fact that you're citing the TOS is not exactly helping your case, since it's well known that basically no one reads those. I'm not as concerned about techy people as I am about the average person's understanding of their identity privacy on Twitter. But even as a techy person I was surprised by how easy it is for a random person to link millions of identities. And I'm obviously not alone given that this post made it to the front page. So when you say "what do you expect really?" - well, most people expect that a random person can't discover their email from their twitter handle. I think that's a completely fair expectation, and people should rightly be concerned about this "feature". Posts like this should be upvoted, because a lot of people aren't aware. Your incredulity here tends to come across as "it's in the TOS, you're all pretty ignorant, I knew about this all along." which isn't all that helpful, even if it's all true.
