I'm not sure which point you're trying to make. Did you look at op's submission?

I assumed you thought scraping wikipedia and putting it on top of the search results was unethical. (The other alternative - that punishing scraper sites is unethical - seemed unlikely). So the fact that you prefer DDG because of this seemed weird, considering DDG does the same thing.

DDG is clearly attributing to Wikipedia and is not cloaking the link behind a redirect.

Google's page wouldn't get indexed in a search engine to try to drive traffic to itself.
