I know absolutely nothing about this company; however, I do know that this argument recently parroted, repeatedly, ad nauseam, is patently ridiculous.
The point is, their writers are not really specialized so they cannot be expected to whip out exceptional papers of any sort. The client will not fail, but he will not get stellar grades either.
Experienced academic writers who are good at what they do routinely write "A" quality essays in numerous different academic fields. If this weren't possible, then,
students would also be incapable of ever writing excellent essays in any academic field outside of their own major courses of study. Meanwhile,
tens of thousands of college undergraduates manage to write their own "A" essays every semester. Every student reading these posts knows that plenty of students write great essays in courses totally outside of their own majors. If an undergraduate Biology major can write a great History essay, and if an undergraduate Economics major can write a great Political Science essay, then, so can many experienced professional writers with degrees in different areas. That's only much more likely to be the case if a writer happens to have
hundreds of essays in those areas under his or her belt, already.
Let's not even get started on the possibility of needing numerous revisions because the writer is not really knowledgable about any topic in particular.
The need for revisions rarely has anything at all to do with a writer's existing knowledge about the topic of a project. Anybody intelligent enough to write academic essays for a living (especially for many years), in the first place, is perfectly capable of reading course materials and/or finding and reading relevant authoritative source material to produce a great academic essay in many different academic areas, and regardless of whether or not he or she happens to have a degree in the same field as every project. The vast majority of revision requests in this business - at least as relates to legitimate writers - are the result of writers accidentally overlooking something in the original order specs, not whether or not writers have their own degrees in the same area as every project.
Remember, writing experience and learning through the writing job is not the same as actually taking the course, learning the lessons, applying the lessons, and graduating with a certification that you really know about a specific field.
"
Taking the course, learning the lessons, applying the lessons, and graduating with a certification" are important only to someone's ability to write about a subject
without using sources, such as in a closed-book/live-testing scenario (and, obviously, to one's ability to perform on the job in a vocational setting after actually being hired as a professional). Clearly, those are two completely different situations. An experienced writer who happens to have a degree in Political Science or Philosophy, for example, can usually write (very well) about many Psychology or Sociology topics if given the opportunity to do some research. Nobody is suggesting that the same writer can answer questions off the top of his head or write about Psychology or Sociology topics without any opportunity to do some research. So, when it comes to hiring a writer to provide an excellent academic essay for a deadline, as opposed to, say, writing a timed closed-book exam essay, what's infinitely more important than the writer's own degree area(s) is the experience of that writer and that writer's reputation for honestly representing his or her confidence level with a particular topic to his or her clients and prospective clients.
