Indeed. Astronomy has two major journals: The Astrophysical Journal and MNRAS. Up until now they complemented each other in their business model. MNRAS had no publication fees, but supported itself with a higher subscription cost. ApJ has publication fees and a lower subscription cost. Papers would require a subscription to read for a longer time on MNRAS than ApJ.

I always felt this system was nice because it allowed younger or independent researchers who perhaps didn't have grant money to publish in a top tier journal. But if one did have grant money one could afford to publish in ApJ and see the paper released earlier.

But it looks like this system is coming to an end.
