I believe that editors who have had the experience of reviewing scientific studies over the years, and now have mentees under their care. Should be a strong point of focus in an advocacy for open science, as it is expected that the experience in handling scientific information might have given them insights into the need for the information to be available to the public.
In an era of plagiarism, a senior researcher might have plagiarized a student's scientific study to publish. Open science, will give the victim the opportunity to address such issues of plagiarized works
