Bing - maybe. DDG - it used to be much more of an alternative, now a little less, with their decision to actively censor their content. Still, they - supposedly - don't collect and store information about you. That's the sense in which they're an alternative. And in Google, there is massive, manipulation of results with all sort of commercial biases. In DDG we don't know that that is the case.

Hmm. I notice they didn't didn't say search results manipulation is not an option.
> Why should everyone have the same search experience?
As far as search results are concerned - so that you don't get to play games with what's more and less visible on the Internet? For the sake of fairness?
> We all have our own preferences about how things should look and work.
Oh, so you want to _flaunt_ how you'll manipulate people's search results to fit your interests? I'm sorry, I mean "the default preferences"?
