A confirmation that authors are tired of paying to publishers. The whole article is nevertheless about the increase of open access journals, which I am not sure is a good sign. My personal experience is that I received maybe 15 invitations to publish in new, open access journals, during the past year only. The publishing fee is always the same, in the 500-1000$ range. And curiously, half of these new journals are published by the same publisher. So I tend to agree with one of the comments at the end of the article:
Unfortunately now too many open access journals are mushrooming & publishing low standard papers just by taking money
Because nearly all the must-have journals still charge subscription fees, the rise of the author-pays model actually imposes an extra expense on research funders
If you publish 5 to 10 papers a year in such journals, you clearly need to allocate some funding for it.
