To me it reads like a final backstabbing against someone who held diametrically opposing views and who no longer has the ability to talk back. If you can't say something nice, say nothing at all. Fully half of the sentences in that obituary list his shortcomings, if that's your attitude then you should refrain from writing an obituary. You don't have to lionize the person or turn it into a hagiography but at the same time you don't have to use it as an opportunity to have the final word and to highlight once more to a much larger audience why you really didn't like someone and why someone didn't fit your view of Mozilla.
