I believe this thread would have a much less dramatic headline if Google didn’t itself kill Google Search ten+ years ago.
Also, it bought most of the examples listed, not made these. It just saw an ads/dm opportunity.
I also remember using Opera on its last original engine and those “Get Chrome” banners which made a whole browser freeze and stutter on anything but Chrome. I’ve pointed that out a few times back then on forums, but not too many people noticed it, it seems. The “our ads our performance” trick fled completely under the radar.
