Yeah sure it take thousands of dollars to make a PDF. There is a bunch of small organizations and universities that manage to have journal free for reading *and* publishing. There's no reason to pay huge fees for "typesettings" in an area where most of this thing in automated. If the publishing pipeline is too complex it's time to remove bullshit and simplify things. Feeding a latex file into a pipeline or clicking on "save as PDF" in Word shouldn't cost more than a few cents.
