To quibble, something can be "unsafe" i.e. harm you in certain ways, and also carry health benefits, since "health benefits" does not merely translate to "life expectancy". In fact for the study in question, compare impact on different organs; for some there is a harm, for others a marginal benefit (if I remember correctly).

This is the problem with pop sci headlines, they don't give you context. If one study finds that some compound has potential benefits in one specific physiological region, the news will read "x is good for your health", and vise versa.

Looking at just mortality, we can more accurately say, for those touting this study, "there is no evidence alcohol consumption improves mortality", and also "low alcohol consumption may weakly worsen mortality rates".
