I think it is not just "ads" but also the character of the ads.
If the ads stay in the boundary areas of the page or well-behaved interstitials that's one thing. In fact, ads can sometimes be interesting and entertaining and most importantly can make markets more competitive bringing you a better variety goods and services.
When they screw up the page, jump around, cover things up, don't have proper controls to "x" them out, use confusing dark patterns, generate fake clicks (ever think it's not an accident that some sites jiggle around so much?), need 50 trackers to be (kinda) sure parties aren't screwing each other, have 20x the bandwidth cost of the content that's something else.
Also there's the content of the ads. There is a subprime tranch that includes Temu but is best represented by prerolls on YouTube that are best advertising sketchy energy drinks and supplements and worse are outright crypto scams. I can see some humor in Temu but not in the scams.
