> I never see Google return phishing pages
Maybe you're not looking or maybe you're lucky.
Either way, many of us see it happen all the time there too. For GitHub especially, I almost never get the canonical repo for a project in my Google results. Phishing or innocuous, it's almost always some fork at the top and then a bunch of non-github.com sites.
Search is more or less "cooked" now, as they say. Google vs Bing vs DDG vs Kagi is mostly in the noise.
