Seems a very liberal use of the word “safe” unless I’m misunderstanding. It could mean either the drug is 100% safe, or that our methods of observation were insufficient to find the risk. Safe until proven unsafe and the class action lawsuits start, as it goes with many drugs.

Doesn’t seem like a particularly strong counter-argument, unless the point is that sometimes we humans like to err on the side of recklessness in the name of progress.

I think you are misunderstanding, the article doesn't just say "safe", the article says "suggests it is safe" (the "suggests" part implies not being 100% certain).
