Yes, I agree that social search can improve accuracy, and that google knows more about its own social information so it can use it more accurately. Artificially inflating that, for the purpose of pushing their product, is the problem (that's how I'd define "artificial ranking" - ranking on a basis other than returning a page of search results for the user). This avoids the problematic term "objective". I don't buy th…
I am not sure about the "antitrust litigation" claim you make. Nobody is forcing anyone to use Google. There are tons of old search engines and new ones coming up every year. This is very different than having a computer where Windows is installed by default, instead of having the choice of your OS. It's like saying Facebook is also "abusing its market power" because it only shows you contacts on Facebook and not on…
Your point about alternative search engines, and Windows being hard to avoid, is relevant for another kind of antitrust.
Aside: though, I think google is still far and away the best, in terms of response time (especially for predicting search queries as you type - that requires huge local data centres all over the world). e.g. Duck duck go has great features, but it's just too slow (at least, over here in Australia). Who can afford data-centres everywhere? (maybe Amazon...) Google also has one of the strongest brands in the world. So, the choice is kind of figurative. It's an earned monopoly, not earned through abuse, not bad or wrong; but a monopoly nonetheless.
