Didn't see where it mentioned anything about subsonic ammo either.
Actually Rich I've spent hundreds of hours in a suppressor manufacturing facility, along with being issued them in the military, own a 1/2 dozen or so and shot most everything out so yes I've seen the insides of many many suppressors, both being manufactured and repaired. I've helped test, worked on R&D and done training for many shooters as well. In my experience, centerfire rifle suppressors do not need cleaning but hey, if you want to clean your suppressors have at it.
As for the mention of "subsonic" in your referring article, there's no need. I have shot literally thousands of rounds through an MP5SD and they are simply a 9mm pistol and the integral suppressor combination combined with ports in the barrel to reduce pressure make it subsonic, hence why they are so quiet. It's also why they are weak on kinetic energy and training consist of short burst or minimum of controlled pairs on target. Had you actually been issued one, used one or owned one you would know.
Lots of subsonic pistol use, integrally suppressed and rimfires do build up lead, carbon and unburnt powder, so YES they do need serviced.
