You didn't actually read the article did you? They weren't talking just about retrospective studies, seeing who gets cancer and whether they took vitamins or not. The article talked about multiple randomized double blind placebo trials.

If you get a bunch of random people, give some these high doses of vitamins and give some a placebo, the ones getting the vitamins did worse.

Unfortunately that says nothing about people who are not megadosing on vitamins or who benifit in other ways thus offsetting the risks.
