When I first started out on the internet, ads were banners. Literally just images and a link that you could click on to go see some product. That was just fine.
However, that wasn't good enough for advertisers. They needed animations, they needed sounds, they needed popups, they needed some way to stop the user from just skimming past and ignoring the ad. They wanted an assurance that the user was staring at their ad for a minimum amount of time.
And, to get all those awful annoying capabilities, they needed the ability to run code in the browser. And that is what has opened the floodgate of malware in advertisement.
Take away the ability for ads to be bundled with some executable and they become fine again. Turn them back into just images, even gifs, and all the sudden I'd be much more amenable to leaving my ad blocker off.
Most people, including folks on here, think cookie banners are a problem, but they are just an annoying attempt to phish your agreement. As long as these privacy loopholes exist, we will keep hearing such stories even from large corporations with much to loose, which means the current privacy regulations do not go far enough.
Even back in the 1990s the internet was awash with popups, popunders and animated punch-the-monkey banner ads. And with the speed of dial up, hefty images slows down page loads too.
You must be a true Internet veteran if you remember a time ads weren’t annoying!
