1) If you're in business, likely you don't care about the privacy of searches anonymised under legal agreements because, well, there's just nothing quite that interesting and if your employees complain, you have to wonder what they are Googling in their spare time that they don't want you to know about.
2) Alternatives. I was an Opera user since before 3.something. It peaked a year or two ago, the developers were moved on, and it's now just junk and uses Chromium backend. IE isn't a sensible alternative either (trust no browser that wants you to go to Bing by default, has the Bing toolbar, etc. either). Quite what are we supposed to use and deploy? Firefox? The MSI and GPO integration is still all random-third-parties that we have to trust did it right and didn't add their own junk in.
Sorry, but on the face of it, the privacy "problem" isn't really a problem for most people. I agree that privacy is an issue and I get more than most people that privacy is just something you should have by default, not be made to justify or fight to get. But, honestly, there's little choice.
And when you're a techy working for a business, you'll deploy what's been agreed on, which will be the lesser of most evils. At least Chrome MSI-deploys and has proper GPO and respects Windows Internet Options, and is cross-platform in other respects.
At home, I still use Opera. But only until websites start crapping out on it, because there's no way I want to touch the newer versions anyway (whatever their underlying browser).
