There's a response to this linked in the article which is a bit more cautious about the ethical issues around this so at least there's that:

I'm a scientist myself so just a comment on how papers are published: journals have an "impact factor" which is generally used to denote journals that are more "important" than others or have more influence, with a higher IF having more prestige and being tougher to get published in. The original paper linked is in BJOG with an IF of 6.531.
For reference, the top science journals Nature and Science have 17 and 41. The highest rated journal now is 435.
Just because something is published in a scientific journal doesn't necessarily mean that it's "good science" or will have much influence on the area of research so I wouldn't take much from this one paper.
(p.s. Obviously impact factor is a bit more complicated that this and has been criticised but just my 2 cents)
