Seriously, you might not like MS, proprietary software, their business models, or lots of other things about them, but don't go blaming them for some cretins attacking their systems in a failed ploy to make a buck.
The Lizard script kiddies had a pretty horrible business model too, FWIW, break into a bunch of systems across the internet to DDoS Xbox/PSN servers, ruin a bunch of people's Christmas, and use the media coverage to sell their DDoS as a service scheme.
It's not that MS was being lax about properly hardening their boxes, though. You could DDoS the most hardened server out there, or a rack of them, it's really an inherent design issue with TCP/IP that you can DDoS systems. It's completely ignorant to blame MS, they didn't have a single point of failure, they had blocks of auth servers nailed.
