From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Did you read it? The author is clearly biased against OpenBSD.

As an example, he dedicates quite a lot to talk about "ROP gadgets removal" (which is an ineffective mitigation employed by OpenBSD), however he also states:

Anyway, removing ROP gadgets the way OpenBSD is doing it doesn’t add a large amount of complexity, doesn’t harm performances nor debuggability, so why not, but it doesn’t make exploitation significantly harder, at all.

When you consider the fact that some mitigations which were considered overkill were proven significant with time (for example, OpenBSD was completely unaffected by Spectre v1 and similar exploits since they disabled hyperthreading), statements like these make it clear to me that the author is biased.

Edit: This is not to say the website is deceptive, it's just that it doesn't provide a good analysis or comparison of the security of different systems IMO.
