OS X's security is by design, not obscurity. Learn something about Unix, it'll do ya good.
What HAS changed is that the Mac's rise in popularity made it a better target for malware that attacks the USER -- Trojans and so forth. Those aren't attacking the operating system. They work through the weak link -- the user.
So your premise is flawed. The loss of Mac obscurity caused a huge rise in malware that could attack Mac users, as it had been attacking Windows users for decades. But (with a few notable exceptions, like the one that is the topic of this thread), OS X is still one of the most secure operating systems in use, exceeded only by pure Unix and Linux, which still benefit from an obscurity of which Apple only has vague memories.
So don't hold your breath for an apology from the Apple fans. They weren't "completely wrong", and you were only partly right.
Be careful now, your face is starting to turn blue... :-)
See there you go again.... Twisting facts to tell more lies.
The fact that no one was attacking them because the target was so small is obscurity. You admit that then you change the definition to suit your needs.
