The quote I argued against didn't specify anything regarding your particular ad network. My argument was pretty simple: the content is more important than the origin.
> Since my ad network doesn't serve any JS from an advertiser
That's about content.
> As long as my browser doesn't load anything from different domains
That's about the origin.
Just because your network doesn't serve malicious JS, doesn't mean all networks do. And just because it comes from the same origin, doesn't mean it's safe.
