It is good to remember that there are many other search engines besides Google that provide excellent but different results without tracking or the weight of Google advertising burden.  DuckDuckgo is my go to search engine.  I personally find Google's advertising burden a very tedious impediment to fast effective searches.

Thus, in many ways, the problem  is far more complex than just having google filtered by legal fiat.  Google does not represent the only database which has the last 25 years of history lodged somewhere, just the only one recognized by 99.5% of users.
