No, Adobe didn't follow through on providing a free license for Display PostScript as promised --- this killed a lot of software companies which had NeXT/OPENstep software ready to go --- of course, Adobe didn't care (they couldn't even bother to keep track of the source code for Glenn Reid's TouchType.app) and were glad to kill off competition such as PasteUp.app

Mike Paquette and the rest of his team spent a decade re-creating Display PostScript as Quartz, née DisplayPDF.
