Higher installed base, higher vulnerability. Hackers have already exploited iPhones with jailbreaking since 2007, so how could anyone believe any platform is more safer than the other? You read articles from websites thinking of more security when hackers can spy through your front cam and invade your privacy as you read this.
People want security when they leave fingerprints all over the net with personal information. It is like putting #8086 as your PIN code because you read four years ago it was the rarest used from an article. After people read it, now it becomes more common and less insecure. So why bother using #8086 when someone is already telling you it is the rarest used? Don't be so gullible, McFly!
