I'm no fan of the Daily Mail in particular or their political leanings in general, but I don't think you're being fair here. It was live for 90 whole seconds and you wrote almost 400 words about how it's the worst thing ever? I agree that they should use Lorem Ipsum style filler text until they have real quotes, but preparing two versions of stories is extremely common. Most news outlets have a stack of "in case of death" stories on file for every possible celebrity or public figure. They even wrote one in case the Apollo 1 astronauts died.
