Weren't those ads always there, though? The most obvious change is that a little AI popup appears on Google search providing a brief (even if hallucinated) overview of what the user queried.
Unrelated, but I wouldn't expect this take on HN where I assumed everyone knew what an ad-blocker was.
I don’t use ad block.
I find that when it messes with the layout or formatting of a website it’s really annoying, and I consider the volume and type of ads an important signal for a website’s trustworthiness.
Oh and plenty of devices don’t have easy access to ad block, like my work computer.
Mobile users (or other locked down devices where adblockers are forbidden) are still a decent chunk of traffic. It's much easier to just read the overview and not click through to the ad infestation, or even use a chatbot of choice as the search engine instead of going to Google, because "websites is how you get spammed with ads".
Yes the ads were always there but that was the most efficient way to get the content/information. That has changed and even with ad blockers, websites are no longer the most efficient way to get to that content/infomation. That is what has changed
