There has been a lively discussion within KDE regarding the Konqueror browser; and subsequently it has been decided that a non-KDE, GTK browser will be the default for the spin.

Why, because Firefox is the only choice for Fedora, Chromium is not allowed.

Here is a good excerpt:

The correct avenue here, in light of the news from the upstream products, is to keep the status quo regardless of the lack of usability. When we finally get a fully-featured Qt based browser, that is when we switch. We DO NOT switch to a GTk based browser that has zero integration with the Plasma desktop - single click selection of files and directories within Firefox doesn't even work, let alone the theming and other issues. Ironically, those two items, as well as integration with kWallet, work fine with Google Chrome (which is not a choice in this discussion).

Tom Calloway has been working on Chromium - and his copr is up-to-date for anyone who wants to try it. https://copr.fedoraproject.org/coprs/spot/chromium/

It's been a slow slog working through the issues keeping it from the official repository, but progress

has been made: https://code.google.com/p/chromium/issues/detail?id=28287

Things have also changed over the years, and Chrome/Chromium's popularity has continued to grow and is now packaged in Ubuntu, Debian and Suse. Firefox has exceptions mainly because it is deemed "to popular" to keep out of the distribution. I think it is obvious to everyone that Chrome/Chromium is "at least" as popular than Firefox.

I realize we have our guidelines and we're not Debian, Suse or Ubuntu... and that's a good thing. But, if we're making exceptions for Firefox because of it's popularity shouldn't we do the same for Chromium.
