> Search for something generic like "computer" and you can see an example of how hard it is to get information instead of ads.

I tried this. The wikipedia page for "computer" was the second result. Above that, oddly, a store page for "computers" at Best Buy. Above that, some suggested questions like "what is a computer?" ("A computer is a machine or device that performs processes, calculations and operations based on instructions provided by a software or hardware program.") And above that, at the top, several advertisements and a map of where the advertising locations are.

I don't understand what you think should come up in a search for the word "computer". I already know what a computer is, and I think it's safe to say that's true of almost everyone using the internet.
