Yes, but &quot;quality&quot; is both vague and subjective, not only will different people evaluate aspects of quality differently, different people will legitimately have different views on what components &quot;quality&quot; of a link has. I don&#x27;t think it&#x27;s unreasonable to consider the source as a one factor in overall quality (if nothing else as a proxy for things the rater is unable to evaluate about the article in isolation.)
