Google, Apple, Facebook are all using Oracle albeit not for their main consumer-facing product but more for internal systems that performs e-Commerce functionality.

He bought FB way too late than most others. What valuation did he buy in Zynga, Twitter etc than we'll talk? Jut because they're 'hot' now doesn't mean that they'll make him money later.
