I'm not convinced how presearch is really decentralized. all they do is redirect you back to google or duckduckgo page, and considering that duckduckgo is also using google results, whatever you do, you use google in the end. (proof that duckduckgo, bing, yahoo, yandex, weibo, and pretty much all others use google to generate their results, can be demonstrated easily. few months ago google tweaked their algorithm to show "black american inventors" when you do an image search for "american inventors". be that as it may, it was just google who tweaked their search results for this one particular search, yet literally all these searches show "black american inventors" if you do image search for "american inventors". while this one example may not affect us as much, imagine what else they are tweaking? and imagine you can't remember edison's name on the spot? so you do a search for "american inventors" thinking, good, I'll recognize him from the picture, and see what his name was, and boom, you can't. I get that crawling entirety of web in order to compete with google, might take some time, but I don't see they are even trying to do that
