This is something I was actively resisting. It turns out that for me, I find GTK3 to be less aesthetically pleasing than GTK2. There are far fewer themes for GTK3, and they aren't as nice as the GTK2 ones either. Sad to see a step back in user interface design, in my opinion at least.

It won't be long before all the distributions catch up and start removing the GTK2 builds, which are likely to be deprecated.

Also because of the extremely irritating animations, which some found impossible to disable.

Theming is a thing of the past. Unless it comes directly from the App Developer. The idea of general theming looking good is pretty stupid.
