User blog comment:Kirkburn/Browsers on Wikia - a Fall 2013 update/@comment-10349203-20131113192757

I guess putting Opera/Presto and Opera/Chrome into the same bucket is not meaningful. There are a lot of Chrome clones - eveyr web-portal may introduce its own one, that is Google strategy. So, actually, Opera/Chrome is not realyl different from YendexBrowser, MailRuBrowser, Comodo Dragon and dozens of those.

What is more interesting is how many Opera/Presto users would downgrade to Opera/Chrome. Because it really is downgrade - they would loose all the control over the browser, over the webpages, etc. Personally, when Opera/Presto would be dead i'd probably switch to original Chrome or Mozilla - there is just no real reason to use a surrogate, when you can use original product for free.

So from technical point of view, Opera/Chrome should be added to Google Chrome bucket.

And from social point of view Opera/Presto and Opera/Chrome would better be coutned separately to estimate how many old Opera users would switch to new Opera/Chrome and how many would switch to other "brands".

And this chart, merging together users of browsers having nothing in common but name just makes neither social sense nor technical one
