You just used the term "making their tweets private". If we can't agree this constitutes a privacy feature - however small in scope - I think we'll just have to agree to disagree. :)
Huh? Using a phrase out of context doesn't mean you can insert it into his argument. He explicitly said, pretty much, "it's not about making their tweets private". Blocking wasn't a privacy feature.
