I disagree, the briefings last year got a very effective message out to the public - starting with wash hands, keep your distance, cover your face. Those types of messages were followed almost to the letter particularly in the early days and many are still going with them now. What messages haven't the vast majority of the public in general got.
Granted messaging has got a lot more confusing latterly as we open up but I think a lot of that has to do with some, (gov't, scientists, business and joe public) wanting to open up more quickly/slowly than others as well as having conflicting interests.
