>you write papers for free

Actually you often pay a couple thousand dollars as a publishing fee to get your paper in the journal after review. I'm sure it's not necessarily like that in every journal, but the bigger ones do it that way. So basically pay them to take your content, pay them to view their content, and do labor for them by reviewing papers for free.

True, but it is the case only in some high end tabloid-like journals, not more regular ones (at least in my field). Unless of course you ask for their openaccess option, then they charge thousands for CC-BY-NC-ND and sometimes more for CC-BY...
