It’s not really the ads on Google Search itself that break it.
It’s that almost every result is some automatically generated spam created entirely in response to Google’s algorithms. And it’s those pages that are covered in ads. Google broke the internet.
You can still get what you’re looking for, but I home in on results that look like forums or other actual user generated content. Didn’t even realise I was doing it tbh. I just mentally filter out most of the shit.
