It seems the reason they've gone for the "no amount of alcohol is good for" precisely because of the existence and popular influence of contradictory claims. They're taking the position that it's the negative effects that have the plausible mechanisms and the associations of low-to-moderate use with sometimes better outcomes than abstinent cohorts that are most likely proxy variables for general health and [former] lifestyle.

(c.f. absolutely no pop-science reporting on supposed therapeutic benefits of cosmic radiation from frequent flying, so the average person hearing about it is likely to overestimate its negative effects rather than wonder if they should be booking a flight with every meal!)
