I hate all that tracking and marketing bs as much as the next guy but if the marketing team is the main stakeholder and is responsible for the budget that won't work. I also might be a bit biased as a freelancer but every team I worked in so far had other freelancers on it and if we strongly recommend aginst a practice but the client insisted then we basically had the choice to either abandon the project (and therefore our current source of income) or simply do what they say. I would love to be on a position where refusing is an option that would not cost me my gig.
