The heart of what I'm getting at is that you cannot be the arbiter of whether or not it's reasonable to disagree about that. As a direct consequence, being cavalier about it will not work for solving the problem. I'm trying to inject nuance into a problem I'm acknowledging exists, not engage in a holy war against the existence of the problem.

If you think reasonable people can't disagree with you about this topic, then fine. Forget that! Instead replace that thought with the idea that a nontrivial number of software engineers - likely the supermajority - will be materially impacted by significantly changing the amount of tracking enabled by advertising. You cannot tell them to just take up knitting anymore than you can tell people who disagree with you to just stop disagreeing with you. If only it were that easy.
