I also don't know if it would apply here. As these are "native" ads to LinkedIn. They don't really label them as ads much. I guess if the <div> mentions ads then it might be blocked.
I dont use linkedin much but I just tested it and it blocked 4 ads on the page.
Which is why I qualified it with "within the tech circle", I'd be really surprised if the precentage of Ad block users on this forum was less than 80%.
If HN is like other tech sites, then it'll be more like 20% than 80%.
