In our case, I just think it's interesting that my webdev friend was trying to ascertain truth about the world -- "is she associated with the project she worked on?" -- and the answer came up "yes!" for her even though it was "Nope" for the rest of the world.
Sure, it's an interesting question of which tradeoffs they should make. But as users, it's not really our responsibility to be concerned about that. All we know is that Google is acting a bit strangely.
To be clear, if Google stayed how it currently is, I'd have no problem at all. I'm just worried that google can go from strange to malicious at the flip of a switch. It's unsettling that they're the only realistic option. DDG has been picking up steam, but hopefully they'll do more than nip at Google's heels.
