“seemingly an unlimited number of zero-day exploits”, is how Symantec describes it. The monoculture created by M$ not only allows everyone to be threatened by random encounters with malware, evildoers who target particular businesses or organizations using M$’s OS overcome every defence. The reason Google switched to GNU/Linux was to escape the Wintel treadmill of vulnerabilities.
At the very least the existence of organizations aiming at particular IT systems using the string of vulnerabilities cranked out by M$ should encourage everyone to use a mixture of GNU/Linux and other operating sytems as well as or in place of M$’s. Making yourself a smaller target or camouflage works. Ask any infantryman.
I use Debian GNU/Linux.
Update – The US executive branch is considering an executive order along the lines of the failed bill on cybersecurity. The idea seems to be to wake people and organizations up about the issue. I can see the possibility of renewed interest in desktop GNU/Linux if public knowledge of the cost of monopoly is raised.
