Yes, so if we assume that cost saving is the only metric that is meaningful and that there should be no legislation or norms saying otherwise, then indeed it follows as a consequence.
Cost saving is basically what drives the market, and thus shapes our entire reality. It's not some side goal of some people, that you could suppress or eliminate - it's the thing itself.
As such, I'm not sure where you'd like to draw the line. There's no obvious, defensible place to do it, not unless you're willing to go back up, expand the scope and fight the entire advertising industry on principle - in which case, I'll agree, because I believe that's where the problem originates and where it needs to be solved.
But that does not make it "inevitable".
