Of course it’s that simple. Don’t let ads run JS. Done.
You’re saying that doing this would drastically decrease ad revenue. Which is what I’m saying too: it’s about money, not necessity.
Would a site like SO be unable to survive without ads that run arbitrary JS? I don’t know. Even if the answer is that they must do this to survive, it’s still insane that content companies let randos inject arbitrary code into their pages. If this is so entrenched in the industry that there’s no way around it, that just means the industry is insane.
Money is a necessity, that's how SO exists, and it wouldn't sustain its current size if it required JS-free network campaigns or tried to sell all ad space directly.
Simple doesn't mean it's easy or realistic. Yes, adtech has major problems but they're being slowly worked on and won't change overnight. This applies to any other industry where you think can just walk in and solve everything if everyone just did X. Reality doesn't work that way.
We know that advertising can work and make money without arbitrary JS. When there’s a clear existence proof, is it really wrong to say that a problem could be solved by not doing the problematic behavior?
Of course reality doesn’t work that way. Ad companies aren’t going to change, because they like money and don’t give a shit about users.
We’re stuck in a local minimum. It’s insane. It could be easily fixed if everyone just stopped doing the insane things. And they won’t stop.
