Google says deleting old pages to bamboozle Search is "not a thing!" as CNET erases its history. The tech news site removed thousands of old articles in a recent bid to appease Google and improve its performance in search results over the past few months.
I don’t think they’re necessarily so much the number of search engines that currently exist (there’s already currently several) but rather that not enough people use the alternatives that Google had the monopoly. (Also helped by Google actively railroading users into its products and suppressing the competition)
