The article explicitly says that the 39% reproducibility isn't that far off what you would probably expect anyway.

The article then goes on to add the the meta-study was awful in it's study selection, giving the example: OSC researchers tried to reproduce an American study that dealt with Stanford University students’ attitudes toward affirmative action policies by using Dutch students at the University of Amsterdam.

The article then goes on to say that reproducibility is still a problem in science, but that the meta-study was simply terrible in it's own methodology. Low reproducability is less of an issue given the context of the problem space, the article says; the meta-study was wrong, both methodologically and in conclusion ('low reproducability' != 'unethical' or 'crisis').

I recommend reading the fine article.
