I also find misleading title where they by cost mean publishing cost.
I find the argument over pay-for-placement journals kind of silly. I estimate it costs me $50,000 to write a journal article. This includes research, grad students, overhead, etc. Based on that, no big deal if it's an extra $3k to get it published!
Also grad students heavily subsidy your journal article. Add extra $25,000 per student if they found job instead.
What concerns me most is that proofreading/editing/typography is burden of researcher.
My optimistic estimate of proofreading/editing s about $5000 including revisions. Here you again subsidy journal/university as you ineffectively do what professional editor could do better with half of time and budget.
