Apple and Adobe have always had a sour relationship. Adobe's crappy font licensing led to truetype and they're crappy implementation of Flash led to Jobs dropping flash in the iPhone just to mention a few things from their history.

Not to mention the fact that there were tons of rumors around Apple developers practically handholding adobe to get them across the finish line for the Apple Silicon port.

Adobe is extremely incompetent wrt actually developing usable, clean and efficient software so I can definitely see this as being plausible

OTOH they’ve used Display PostScript and PDF as their display systems for NeXTSTEP and Mac OS X.

Only MacOS Server 1.o used display postscript, every version since has use Quartz or Quartz Extreme ( also know as Display PDF).

Apple was an early investor in Adobe.
