> Eg, DDG always fail the "watch (specific movie or tv show) online" search query test. Many other search engines like Bing and Google also fail.
DDG results are mostly Bing results, so if a page doesn't show up on Bing, it probably won't on DDG either. That doesn't mean DDG themselves censored the results.
As a user that distinction is meaningless. I don't care what they use as a backend, and I shouldn't have to. If their source provider censors search results it means their own search results are censored too.
