What is the alternative to prestigious journals? Each scientist should read all of the papers published in their field every day?

The work of curating a journal for various metrics (subject matter, standards of peer review, impact etc.) is crucial to the everyday working of science. This doesn't mean that a few for profit corporations should get to extract profit from it, but it also doesn't mean that academia should give up the whole idea and just read all of scihub or arxiv to make up their own minds.
