If anything google should downgrade the daily mail even more. Not for its content (which i personally dislike, but censorship is a risky business), but rather for its spammy practices and clickbait titles.
If I search for something and it's related to what I'm searching for then it is not useless.
If I pay an offshore content farm to do content stuffing, do you want my gibberish in your results?
Then it becomes a question of which algorithm you want. Filtering out daily mail bollocks is the kind of thing that keeps me coming back to google. Am I concerned about the implications? sure; but here and now, it's doing exactly what I want.
