It's perfectly clear.
Or are you arguing that people need to know the numbers but have no obligation/ability to actually figure out what they mean?
Yet, whenever I try to look up anything with regards to health/medicine, I find dozens of people/orgs repeating the last bit, and the first bits are hard to come across if you dont already know where to look. Its so avoided that im not surprised some people think its intentionally hidden.
Saying something is safe is a declared risk tolerance, it is not actually communicating the risk. It only works if the people you are talking to already trust your judgement.
Taking a complex topic and distilling it into simple, consumable bites that your audience can injest is what communication is. Yet, so much communication takes the easy route of "the public cant possibly understand this, well just say its safe or unsafe".
If you see this as an unavoidable, then I see the breakdown of trust of these institutions to be unavoidable too, as their ability to communicate is too poor.
They publish information at every level of specificity and detail!
Anyone who is actually curious and not just doing this lazy meta-commentary game could find all the information they need at any level of specificity or technicality they want.
