Actually you've been talking to Natus, Inc. and the person you wanted to correct is Natsu, LLC. Because we're completely different imaginary entities that merely happen to share an account, you're actually the one who is confused here. Hopefully this clarifies things for you.
On a more serious note, if I can't hold the owners responsible for their actions via their own subsidiaries, then what? This is why I find them to both be 'Sony' enough to share blame and I don't particularly care for it when people try to play shell games with corporate identities. The particulars of their corporate governance are simply not relevant to what I was saying.
