Hundreds of millions of Internet users were annoyed because of Windows botnet-based DDoS aimed at one (1) person.
... Some people out there used no fewer than six Windows botnets to go after this one guy. And, in the process, they knocked out, for hours at a time, most of the major social networks.
It happened because Windows is an insecure piece of junk. Anyone who knows anything about security knows that this kind of disaster was only a matter of time. Windows botnets are responsible for DDoS attacks and most of e-mail spam. You cannot secure Windows. Microsoft keeps saying that they will, and they always fail. Period.
Reasonable people have been saying the same thing for years. Botnets have taken down more important things, like hospital networks, and have been fingered in power outages. What kind of real harm will it take for people to give up Windows and move on to sane platforms like GNU/Linux?"
