The federal government argues Google has smothered competition by paying companies such as Apple and Verizon to lock in its search engine as the default.
DDG does have better results than Google. I've not used the latter for years and was surprised by the bad quality of results when I used it once accidentally last week.
It depends and that’s why both your answers aren’t quite the full truth.
If you are a deep resident of the Google ecosystem (maps, Mail, android etc.) Google’s results are second to none. That’s because Google knows exactly what you care about and what is relevant to you. They know where you work, where you are, what you talk about etc etc.
With all that knowledge google can optimise both ads and answers to you almost perfectly.
If you’re not a deep resident, ddg is better - their results have to work harder, so to speak, because they don’t have your every waking thought to hand as a relevancy scale.
So, yeah, if you give Google everything they make money off it and keep you dependent on them.
