I don't know who reviewed this, but having nine if the first 13 references being self-citations certainly makes me feel concerned.
Clearly this author has an agenda to push - and that's not necessarily a bad thing - but I'm not sure that this reliance on own published work is a good indicator of evidence-based science. For sure, in the first paragraph alone there are incidences of statements that have no reference, for which I would definitely expect one or more. Basically, if this was scourge of undergrad work, regardless of its message, it'd be looking at a lower second. I'd expect far more from a career scientist. With this in mind, it's hard to take it seriously.
