I don't understandd how that can be a legitimate mindset for Canonical.
Ubuntu is on the verge of becoming the major player in the early-stage linux convert market. They have the best supported platform, the largest and most accepting community and userbase, and are beginning to branch out towards more traditional markets like gamers with the soon-to-happen inclusion of Steam.
It would seem a better move politically to make this feature either opt-out or opt-it, and not required.
I've used Ubuntu's dash search when looking for an app that's not readily available. Who keeps things on the desktop nowadays? :)
