The risk profile is not the same as eating undercooked salmon that is not intended for raw consumption.
Depending on where you are the salmon might be less likely to contain parasites and your government food hygiene institution might not consider raw salmon unsafe.
My point is that the original comment seems like US-defaultism.

Bacteria appear when preparing the meal. A salmon, uncut, is internally sorta safe, but once cut open, bacteria is introduced.
This is why you don't see cuts of salmon for sale, at room temp. You see cleaned salmon on ice, or in a fridge.
