I'm not at all sure that I do know. I believe part of the implied message in this post is that Google is not motivated by a cynical profit motive to the same extent that Amazon is. That is highly dubious to me. Sending search queries to Google may very well be both more useful and less surprising to end users, but it is NOT "less evil". Either and both would be significant privacy violations.
I am now not sure that is implied by the message at all. In which case you would be mistaken about me knowing damn well what it meant. I have no idea what other interpretation of the Google reference would make sense.
Either way, your hostility is unwarranted and adds nothing to the discussion.
Google, as a search engine, is a generic "find the most relevant thing based on the keywords I provide". Amazon, as a search engine, is closer to "find the things I would be most likely to buy based on the keywords I provide". The two functions are entirely different.
I didn't make any comment about it being "less evil" (was that intended to be a quote?); I was making a comment about the intended function of the service. I could have substituted in DDG or Yahoo! or Bing and the point would be the same; equally, it makes as much sense to provide Amazon-based results to me as it would do to provide results from Target or Walmart.
No, of course you didn't say anything about it being less evil; but that is what Richard Stallman is talking about. So your position is that this is a usability issue with the "feature"? Your comment is baffling to me now.
