That's an amusing reductio ad absurdum, but most people don't have that much of an objection to ad-supported media in principle, it is a time-honored business model.

But being an asshole about insisting that everyone log in so you can target them individually isn't actually a requirement for the business model to work and be profitable.

At most, you can justify being an asshole about insisting that the user not be using an ad-blocker (with the user having the option of logging in with a paid account for an ad-free experience).
