Ok? The point still stands that advertising ultimately pays for the content. Manufacturers buy raw parts first and then recoup the costs by selling the final product, does that mean consumers aren't actually paying for the business?

Security is an eternal problem and a completely separate topic from advertising as a business model. Do you suggest we stop using email because some people got scams and viruses? Or can we talk about communications while acknowledging that it's separate from implementation and UX issues?
