This is tripe. He completely misses the point and instead goes on to list other, unrelated projects that have overcome some of their problems. Notice he doesn't say "Android doesn't have malware", while the original article (and many more before it) say "Android has malware". True, anti-virus won't fix the problems, and true, there is unlikely to be a traditional "virus" on a mobile platform, but that's not the point. The point is, malware exists, and it exists more on Android than other mobile marketplaces. Remember the definition of malware, don't get tied down into the Windows classification of a virus. Malware is a broad term.
Instead of shouting and screaming and dismissing the claims with the wave of a hand, we should be working to eliminate malware on mobile marketplaces. Chris says malware isn't inherent to Android but the fact remains with an open market and training users that sideloading applications from a random website is safe and acceptable, malware IS more inherent on Android. None of their competitors allow for this kind of free and easy installation of random applications. Google needs to figure out how to stop malware without destroying the very thing that made their OS popular (the open platform).
