Am I the only one who finds this a little disturbing?
I mean the thing is beautifully produced, no doubt, I don't want to take anything away from the skills of the people who made it.
But the slickness moves it somehow from "scrappy bunch who gathered all the open data & collaboratively figured stuff out" into a different category. More like "someone with very deep pockets wants to tell me a particular story". Like getting the sort of 10-page glossy brochure they use to sell manhattan penthouses, but it's from the local animal shelter... and there's nothing wrong with the kitten pictures, the photography is excellent, but you wonder a bit who paid all those professionals, and why.
But carefully weighing evidence and doubt isn't exactly the core idea of the art world. You will win few prizes by pointing out factual mistakes in others' work. (Not saying I know of any factual inaccuracies here, to be clear.)
