Opera is not, as an entity or in terms of identity, a fork of Chrome.

However, it is, as rendering and JS goes, functionally a fork of Chrome, since as you'll notice from the source you cited, it uses Chrome's "Blink" rendering engine and Chrome's "V8" Javascript runtime.

Also from the link you cited:

>On 12 February 2013, Opera announced it would drop its own Presto engine in favour of WebKit as implemented by Google's Chrome browser, using code from the Chromium project. Opera Software also planned to contribute code to WebKit.[29] On 3 April 2013, Google announced that it would fork components from WebKit to form a new rendering engine known as Blink; the same day, Opera confirmed that it would follow Google in implementing Blink.[30]

>On 28 May 2013, a beta release of Opera 15 was made available,[31] the first version based on the Chromium project.[32][33] Many distinctive features of the previous versions were dropped, and Opera Mail was separated into a standalone application derived from Opera 12.[34]
