With the recent release of GNOME 3.6, once again the GNOME developer cabel have managed to royally upset their third party developer base – in particular those who develop GNOME Shell extensions and themes.
This blog post sums up the attitude of the GNOME developers nicely and should be required reading for anybody who thinks of developing an extension, theme, or application for GNOME 3.
GNOME Shell 3.6 is not about freedom to customize. It should be – but unfortunately it is quickly becoming a walled garden. This is what happens when you let a small group of UX designers control a project.
