Well, since the figures I've seen bandied around are that protection from this level of attack would be about USD100-200K per annum, this effectively means that unless you have a lot of money or a company willing and able to pay what amounts to protection money, you potentially won't be permitted to speak - doing so with an uncomfortable topic for someone gets you knocked offline. Pay the wrong mob and you get to pay again, and again, and again.
One potential outcome may be that truly personal sites will become impossible to support and host; especially if you have any content that could be seen as controversial. You will have to pay someone to host it for you. If they agree, and it doesn't cost THEM too much, and it's not controversial - fine. Want to promote a social cause? Sorry, you can't afford to. Get back into the bit mines, peon. And this fits nicely into the whole cloud thing too, where you don't need anything in your own datacentre, host it on someone else's computer.
I'm waiting for the first wave of destruction to hit the major cloud providers - if this network supposedly of DVRs can deliver 1-1.5Tbps, and you factor in another dozen of similar size, you're talking 15-20Tbps directed at a target. I doubt even Google and the CDNs can withstand that for very long without service impacts, and that's not even factoring in attacks that actually have a little brainpower behind them.
