This assumes a fixed definition of “good.” I would argue that the search would be better because it was done using data collected only from parties who have given consent.
You can define “good” in terms of cost, revenue, sampling bias, relevance, etc. I can define it in terms of ethical data collection and usage. Who’s to say which definition is correct?
