As the questions are political, you need rhetoric. As unfortunately as it may be, it should be obvious by now to everyone following politics that being "polite" is not a winning recipe in the game.
It is interesting to note that not only is the campaign a clone, but it is in part headed by the same people [1] who were involved in the tobacco business.

By this I don't mean a copy editor, but the person who decides who to send the manuscript for review, and makes the decisions on whether the manuscript is rejected, accepted, or more review is needed. Doing this job properly basically requires a researcher with experience in the field the journal is about.
It appears there are many journals where no editor is employed full-time by the publisher. If all of them are unpaid, then indeed the journal operation should be cheap.
There are however some journals (iirc Nature and APS journals are like this) with professional editors employed by the publisher.
It's also useful to note that the money and working condition issues are country and field dependent. For instance, in many European countries PhD students in many STEM and also humanities fields are most often employed full-time with standard work contract(s), with OK salary (but less than in industry), and full benefits with excessive unpaid overtime in principle forbidden, small or no tuition, etc.
The situation with academic career prospects after PhD as I understand however is that situation is similar to US everywhere, and going eventually gets tough after that point, and most people are culled before finding a "permanent" position.
