If you are a Scientific or Medical Journal, whose business it is to publish Papers and collect advertising dollars or subscription fees (or both), then it's part of the Editor's job to vet errors that are common in Scientific or Medical Papers. Such as this one identified by the article.
If there is but one Editor, then that person is required to complete all the tasks expected of an Editor. If there is money for more staff, then it's the job of the Editor to assign duties to junior employees to do such grunt work, and then it's the Editor's job to monitor these employees and their work. Again, the ultimate responsibility is the Editor.
If you publish online or in print, you need someone, maybe it's you, maybe it's an employee for hire, but someone none the less, to perform this task. It is not optional. Yet for some reason various "publishers" show their lack of skill at their chosen profession.
There has always been bad magazines, journals, and newspapers. Generally they went broke because people would punish this behaviour by not buying whatever it was they were selling (advertising, library subscriptions, individual subscriptions, etc) and they would mercifully dissapear.
Today we can add blogs and online news or science sites to the list. The average internet user has shown themselves to be less discerning than the print reading public of the past, when the dull and stupid simply didn't read anything.
Today everyone from moron to genius reads online, and there is money to be made from serving ads to the idiots of the world, as they can be reached at an economically viable number.
Maybe we will someday return to a publishing world where the poor examples of the art flounder and die. Regardless, if you don't have an Editor or someone performing an Editor's function, you are putting yourself firmly in the lot of the un-dererving of respect. Journals who would like to instead be respected should be vetting submissions for these well-known (amongst actual Science and Journal Editors of competence) errors and correcting them before accepting the paper for publication.
It really is that simple.
