Banshee is going to be the default music player for Ubuntu which makes me worry. Banshee is based on the controversial Mono technologies developed by Novell employees. Richard M Stallman has warned against Mono and C# which applies to Banshee as well.

Insertion of Mono-based software like Banshee endangers Ubuntu as it makes the parent company more reliant on Microsoft and more sensitive to Microsoft extortion

Steven Rosenberg has just published a rave (finally!) about Ubuntu 10.04. He particularly likes gThumb, which can help remove Mono from Ubuntu.

Refutation of Mono disinformation about Banshee being a GNOME project without associated issues

Before I begin this essay, I would like to go ahead and pre-empt any attempts to make me out like I’m a Mono shill. I’m far from it. The only application that uses Mono that I found remotely useful was F-Spot. I see no point in running Tomboy when I can just use Gedit (since files are opened in multiple tabs, just like EditPad).

AFTER persistently ignoring those who warned about Mono, Canonical finally follows Fedora's (Red Hat's) footsteps and takes a closer look at the Mono licensing question. Here is a new statement...

Progress on the argument for GNU/Linux without Mono as a dependency

Mono lock-in potentially increased due to Novell's Banshee in Ubuntu GNU/Linux
