Oh yeah, those price tags are insane. They're making crazy profits of public money thanks to hiring schemes based on impact factors :/

I like to keep the submitted version after review but without editing on my public repositories. Even when I publish open access.

I like the general direction of that idea. But honestly, not sure if this should be national with all the political pressure and censorship that could come from that. With how international scientific research is, perhaps the UN or a newly formed international organisation could oversee such journals.
