I think people are disagreeing with you because the parent comment is referring to Linode platform security and not the security of the individual VPSes -- which is a valid point. The security of your individual VPS depends, to a certain degree, on the Linode platform's security.
But I find it disheartening that multiple people chose to just downvote you, and nobody bothered to write a response.
I came to the same conclusion but what good is karma if you don't get down-voted occasionally?
I didn't misunderstand the parent's comment ... I was just providing a data point on the continuum. My experience with Linode has been great. I do realize that there have been security problems with the platform itself.
