I guess that’s why the journals insist on copyright transfer.

At best you get a ”copy” you can share via email when asked personally; the equivalent of a musician paid a couple drink coupons to share with their friends that came to see the gig…

I'm not suggesting to publish every paper twice. The author submits only to one of the two journals. If it's the original journal, the article appears exactly as is common now, behind a paywall, and that's it. If it's the new sibling journal, the publisher of the original journal has nothing to do with it, no copyright transfer occurs, and the paper appears only on a free and open platform.
