Your browser supports Web Environment Integrity (WEI), which is harming the freedom and openness of the web.
WEI is Google's attempt to lock down the web. In short, a Google-owned server will be asked to confirm that the browser does not deviate in any way from Google's accepted browser configuration. This can used to prevent users from blocking ads, trackers and other harmful content. It allows website owners to lock out users of unapproved (non-Chrome) browsers, unapproved operating systems, and older hardware. Not only would this further cement the Chrome's monopoly, but if WEI is allowed to become widespread then Google could even consider making remote attestation mandatory for websites: non-participating websites will be downranked on Google Search and labeled with a "security" warning in Chrome.

Please use a WEI-free browser such as Firefox (recommended), Safari, Brave, Pale Moon, or GNOME Web.

In this post you'll find a family tree and timeline of operating systems. I have tried to include all operating systems, no matter how old or obscure. Of course, a complete list is virtually impossible, as there is no way to catalogue all the tiny hobby and embedded systems that may exist somewhere.
Please also note that I only included a few selected Linux/BSD/Solaris distributions (it is arguable whether these should count as an OS on their own or not).
Currently, the family tree includes between around 1,120 different operating systems (including some renamings). Tip: use Ctrl+F (Cmd+F on Mac) to search for a system.

Big Update August 2021: Thank you for everyone e-mailing me with suggestions after this webpage got posted on Hackernews by someone. I have added most of the suggestions, such as missing operating systems and a few mistakes.
Big Update February 2023: I added another 200 or so operating systems and made some corrections.
