Since when has Register become a marketing mouthpiece for Linux. It is a ridiculous headline with nothing much to do with the article.
Developers of end-user systems are best to stay away from Linux which because of its monolithic kernel is less secure (OK, maybe I'm not talking about Windows!). Particularly with the Meltdown and Spectre bugs more security that partition Kernel and User space is needed.
Linux is good for speed – but it gets this at the sacrifice of security. Linux is good for well-managed, seldom-updated environments like servers, but a poor choice for end users.
