Adding to what Terr_ already pointed out:
> It's efficient
Money may not be changing hands, but a lot of information is, which is easily worth more. Leaving out these costs are yet another reason why advertisers have a reputation for dishonesty.
Also, the article specifically discussed the terrible power efficency that is always going to be associated with the extra transfer and processing associated with fetching ads. Or do you think they get to violate conservation on energy to be downloaded? If you are adding ad to a page, you are making the client pay more to see it. Offloading costs like this - while pretending it is efficient - should really be criminal.
> It's passive
Bullshit, and you know it.
The very idea of advertising is to be distracting. The arms-race we've seen over the last few decades where advertising went from simple banners, to popups, to various other dynamic rendering tricks, to the modern modal/click-through video ads - and worse - are all about not being passive. This is suck a basic concept in advertising that I have to conclude you are dissembling deliberately, or are such a "true believer" in advertising you cannot see it any other way.
Also, it takes an incredible amount of energy to ignore ads. Anybody that thinks ads don't cost any mental energy is either lying or addicted. Install an adblocker and use it 100% reliably for several months to break the addiction, and you will be shocked at the energy advertising wastes when you see it again.
> It's accessible
Except if someone is poor, they cannot afford whatever it is you are advertising. I've seen this meme a lot recently, so it's obviously a talking point the advertising indujstry is using to try to justify their drain on society. You're not fooling anybody, and this kind of appeal only makes advertisers look desperate.

> It's secure.
You don't get to exclude malware, when advertising is the vector.
Even ignoring that, leaking tracking information makes you malware!
