It sounds like you're agreeing with the article - things work on Linux when you have a deep understanding of them. While it's good to encourage a deep understanding, the group of people using any given OS will always follow a curve of some sort. There will always be beginners; there will always be people who know just enough to be dangerous; there will always be experts.
Requiring everyone to be an expert will prevent Linux from being a dominant OS, because most people do not care enough to gain a deep understanding of any OS, so they'll pick one that's easier to learn the easy bits.
You'll hit the same problem with any OS. OS X will just get slower and slower, and Windows will become infected with malware. General purpose computers are not easy to use, yet: with the infinite flexibility they provide, there's infinite opportunity to fubar them. The average Linux distributions exposes the flexibility by default, making it seem hard to use. But if you switch to a less-flexible Linux, like ChromeOS, many of the problems go away. So I don't really understand what the article is trying to achieve other than trolling by stating the obvious in an inflammatory manner.
