In previous threads about Github being DDoS'd, I asked the same question.

Apparently it's some scheme to ask ransom from companies/startups that have enough money to pay and/or not enough infrastructure to sustain the attack without giving up.

Yep. There's a well-written article about an early DDoS extortion attempt where the victim fought instead of paying, developing some novel protection technology in the proces: http://www.csoonline.com/article/print/220336

Yea, all of us successful web companies face these all the time. We get them multiple times a day. Most of us end up giving up and pay for Arbor gear and ridiculously over provisioned pipes as well as good relations with our hosting facilities.
