Frankly, though, the reason that I believe Bing kept winning for me is that for these really popular core queries, the results were very similar: Bing simply selected more useful text snippets from news articles (letting me avoid clicking results) and weirdly even had better page titles, so it made what was overall the same results more pleasant to use. When I selected my own queries, though, the fact that Google continues to (and will forever) have a larger selection of the Internet available to its search engine became the deciding factor, as it would surface a few interesting things that Bing wouldn't catch.
What I thereby obtain from Bing it On! is not that I want to switch from Google, but that Google has too much power at this point: they are probably forever going to get my search queries simply because they figured out how to index the web extensively and efficiently before "how to build scalable systems" became more general knowledge (although some of that is actually due to Google, so there's this part of me that is saying "shut up and be grateful"), but now that they have this lead there's no real way to kick them down, even if someone else has managed to use the data they have more effectively.
But I agree that google is not what it used to be. They have a weird hunger for our data. But it's not just them, all web companies have become very aggressive in getting our data, it feels like we're being watched the whole time. It's exactly the opposite of what the internet was early on, it's almost like a change in the philosophy of the web. And not for the better.
It seems like issues that famous people have, that they lose privacy at the price of fame, that whatever they do is public, forever. We all lost privacy and we didn't even get fame!
