I'm generally not against this particular sort of design, mainly because it doesn't pretend to be a "normal" webpage. It's a very specific sort of guided presentation.
I'm in general not against it (as I use reader mode) but given the fact that people died in this crash and that this is an official website a more simple design should have been used.
Do we have a similiar term for overdesigned websites which makes reading them feel like doing hard work?
