This one is pretty good too: I guess you have to decide if you are a GNOME app, an Ubuntu app, or an XFCE app unfortunately. I’m sorry that this is the case but it wasn’t GNOME’s fault that Ubuntu has started this fork. And I have no idea what XFCE is or does sorry.

The GNOME devs quoted in TFA seem to labour under the misapprehension that GNOME is not part of a wider ecosystem, but that GNOME is the ecosystem instead.
