I agree with you that I’d like to know what the new evidence is.That article is quite damning about mask wearing. I'd be interested in knowing why they've changed their minds. Maybe it's just a balance of probability. I like knowing things and the reasons.
However in the meantime I’m going to trust what the WHO recommends.
Maybe those points In the article you linked haven’t been negated but they think the positives to mask wearing outweigh the risks, who knows.
