Well, I guess it's inevitable as long as I'm using a proprietary operating system. I don't expect Apple to be any better. Heck, even Ubuntu nowadays comes with ads that you need to opt out of.

.... but some searching indicates that they won't get around to disabling online searches by default until Unity 8 is default in Ubuntu. It seems that Unity 8 won't be default until 16.04 [1] or later [2]. So I rescind my previous statement. Canonical deserves as much scorn as you can dish out for disregarding their users' privacy for 3 years and counting.
