So what do I think?
Since you ask: every browsing device my family owns runs some sort of ad-blocker. That will continue - this article hasn't swayed me. And along with every other commentard here, I simply don't understand how the word 'ethical' can share a sentence with 'ad'.
El Reg, why don't you ask an individual in advertising to write you an article where they justify just why we should tolerate their ads in our lives. It would be helpful if they agreed to also publish their levels of income and debt, so we can determine whether they are driven by the flame of pure righteous belief or whether they are driven by grubby concerns of the wallet.
We will of course provide ethical, constructive feedback for free via the comments section. Even though this possibly makes us 'the product'.
