Re the grammatical errors, my take on it is that "modern publishing" is becoming synonymous with low quality.
Once upon a time, the Editor at a publisher was in charge of editing manuscripts. These days, the Editor is just the person who selects which books s/he wants to champion for publication. Manuscripts have been replaced with Word documents—they don't even call them manuscripts any more; they call them files—and the file is sent off for electronic typesetting.
The job of editing was pushed off onto literary agents, and now many of the agents are pushing it off onto the authors. These days, files are expected to be "ready to print" when submitted by the authors.
