The author of the article can't even be bothered to keep his server up-to-date (my first attempt at viewing the article bounced me with a warning that suggests he only has obsolete crypto protocols available for SSL—why bother with SSL at all, then?). He's quite correct that this initiative is going to come to nothing.
There are currently only four web rendering engines that could be considered remotely usable as daily drivers: WebKit, its fork Blink, and Gecko, with its fork Goanna. WebKit and Blink both have major corporate backing (Apple and Google respectively). Gecko has the Mozilla Foundation paying the major bills. Even Pale Moon's Goanna has multiple people working on it (and since it's my daily driver, I know it has persistent issues with a few sites that have to be papered over with extensions). And the rendering engine is not the only thing you need for a browser, just the largest single part. A one-man project starting from scratch is not going to be viable in this day and age.
