Just wondering, are they currently lying about having made these guidelines before? I haven't heard anything about that myself. I also do remember some news articles saying the government's mask guidelines were so hospitals could stock up (maybe it was once they flip flopped, I forget, it was over a year ago, but I do recall reading that).

I think it's possible they deleted old content to make sure invalid data isn't out there on the web to be cached, linked to, quoted, etc.

However, if they really are lying now (i.e. making current statements) saying that they never flip flopped, then yeah that would be weird.
