Re: More than enough
The author of this article does make some misinterpreted remarks about security, and the quote given had very litte to do with security. This was brought up by Simon Peter on the Matrix channel for helloSystem, and what he meant was that you can't aim for total security: the user ends up with no freedom, the system becomes a maze, and in days new malware gets released that finds another hole to exploit.
Look at Apple: macOS and iOS are locked down to the point of barely being usable, and _still_ have security holes.
