It is now common for some peer-reviewed journals to offer paid editorial support for language editing and translation to authors. Is this perceived as a moral hazard? I would say it depends on the particular circumstances. What do you think?
We have also received such mails from top journals. I don't see any conflict among authors of the submitted article or between authors and editors or reviewers from these statements. It is highly possible that XYZ journal is an open access journal which has a hidden financial nexus (an agreement/understanding) with this journal. Therefore, it is a moral hazard. Some publishers implement Transfer service for rejected manuscripts. If you observe the list of suggested journals, predominant journals belong to open access category.
Not a strange response at all. This practice is typical of specific publishers that selectively consider author profiles and affiliations before considering submitted articles. Such actions should be discouraged and confronted from a moral and transparency standpoint.
