Omni bar solves an obvious problem: the vast majority of the time showing a DNS error is way less useful than guessing where the user meant to go. That’s the alternative.

If I set my default search engine to Mojeek and type in “spotify” will they not suggest spotify.com? If I type in “sp<tab><enter>” is that taking away my agency from potentially going to spootify.com instead?

I am game for a conversation on the power of defaults and monopolies but that’s very different from saying suggestions are bad because people should just remember everything.
