Thing is also that houses that have crumbled have crumbled and there's nothing left. You can't quantify what happened so easily. Articles stay online. Actually that's something that might be good to think about : for a magazine or a journal that decided to make things better and do more responsable journalism, should they delete the content that doesnt fit that bill anymore ? Kind of like the YouTube Kurzgesagt channel when they were confronted with a few of their faults and decided to eradicate the content that was problematic ? It's pretty radical but it sends a message. Not sure how that would be doable economically though.
