Of course publishers will still show adverts...but if your main source of revenue drops 50% overnight - that's going to be a huge problem for a number of content creators...which is what Facebook are warning against.
Most of FB's revenue is direct inventory sold - so this won't be too much of an impact on their owned and operated inventory - but as I say, it's publishers who rely on Facebook's targeting to generate high eCPMs to efficiently monetize their audience that will suffer most.
