None? I have no clues what marketings goal are and frankly I don't care. If they want to insert some junk.js into their web page they need at least to ensure it is legal.
Not really, no. There are 500 people in marketing organization and I doubt there are less than 20 conflicting end goals within that organization. Unless you're going all fluffy and talk about company goal as said by the owners.
Either way, if their process of reaching their end goal included steps which legal dismissed then they needed to go back to the drawing board and figure out a new strategy, right? It would be strange for me who doesn't work in their profession come and tell them how to solve their issues.
