This is rather worrying for fact checkers and those that want to track changes to news articles. The amount of times I've seen articles either get silently edited or go missing entirely is far higher than I'd have liked.

The Internet Archive at least provides one solution there, especially given the somewhat dubious practices Archive.is/today seems to be up to at the moment.

But I suspect that's probably another reason these sites don't want their work archived.
