I did read the article. They go into the history of modern deodorant and antiperspirant and the marketing of them. They talk about how antiperspirant is safe to use but the narrative that it causes cancer keeps growing regardless of what scientists say. They also relate having conducted an experiment with deodorant instead of antiperspirant and how many people could probably get away with just deodorant.

At no point do they say we should abandon all hygiene.
