> I don't know a single person that has ever fallen victim to a virus or malware on linux, and I've been using it almost exclusively for the past 20 years. If it was a threat vector, it clearly wasn't a very big issue.

Yes, well, the ground is being prepared to turn desktop Linux into a Android/Windows like app system (/ wasteland) where users mostly download third party proprietary apps and devs push updates directly to users with minimal oversight.

In this brave new world, you will definitely appreciate app isolation.
