I guess any change to something so big as google search is not simple per se. But my problem is that I think this is their business decision and not a technical problem that needs to be solved as I remember a thread here mentioning that even engineers at Google have a problem with this (that is, personalized seach results)
Since you are on HN, I assume you either are an engineer of some sort or something close to that and you are working on some product, so I expect you to know that the answer to questions that begin like that is very, very often “more than you expected”.
(I would like the option of a “neutral” Google Search too)
