I didn't know about Project Shield and I think it's an interesting initiative. However, for some reason it leaves me a bit unease (not as much as the idea of being taken down by a 650Gbps DDoS at will!) - not sure what it is, but we might be moving towards an Internet where only the "approved" would have "free" speech.
I really hope ISP naming and shaming takes over, so we can make DDoS a little bit more difficult.
