How are their costs significant? Web hosting is extremely cheap. As far as I can see their only really cost is staff to arrange reviews (which is surely a very low paid job).
Everything else they might do - collating papers into a physical journal, complaining about bibliography formats, etc. is superfluous nonsense that nobody really cares about.
Look at arxiv - the only thing it's missing that journals have is reviews.
