This slide deck starts off like any other. A bit of backstory, a bit of self-promotion, no big deal. This is all reasonably mundane, until about slide 10. Slide 10 makes it achingly apparent that you're now listening to a zealot. No amount of logic, evidence, discussion or negotiation is going to change this fanatical mindset.
Slide 15 also caught my eye as being counter to logic. I wasn't at the talk so I can't speak from context, but a slide stating a lack of corporate involvement is a bit striking given the number of gnome developers who work for Red Hat, and the amount of money RH puts into Gnome.
Have a look over the slide presentation yourself. Have a look at slides 10, 15, 23, and 33. Drink in what this means. I've have used gnome for over a decade, but in light of recent events, you'll find me in XFCE from now on.
