I rather took it to mean marketing is BS [emperors new clothes] it is selling something to someone with a BS message [ as in the emperors new clothes] which is indeed what advertising/marketing does IMHO
The fact we are discussing it, have noticed it and publicised it shows it worked in that we now know of that ham/advert.
We could, I assume, discuss whether it was good or bad[effective] but it does rather seem to have advertised the product widely and brought it to peoples attention as I did not know of it before this advert
Granted a vegan may not be their ideal demographic though [and the marketing bods may just know this.] and perhaps itis a world famous “ham maker”
