This is an explicit agreement between the customer and content provider. YouTube, Google search, etc don't have any explicit agreement with users in this regard -- the ads just show up.
The TOS says it, your understanding of their business model conveys it, but at the end of the day they just shove the ads in there without directly claiming to their customers, "you must see ads and be tracked to get free content".
I think usage would change dramatically if they actually claimed this when a user first uses their service.
