I'm aware of that. I would say that's the main reason why they are popular with all the rowers, but I doubt it's why they are popular with gyms for example.
Note of interest, when I was a junior the concepts started to become popular. I was training mainly on the model B, which sounded like a jetplane, incredibly loud! It was such a change when they brought out the model C. I have never seen a model A in real life, but they sure look like made in a garage.
The other reason they are popular with gyms (and boat clubs) is twofold; they are virtually indestructible, and whenever do need to replace worn parts, their product support is ace - details manualed, schematics, and parts, even for that forty year old model A.
This support extends right across their lineup - at big regattas, they will be there doing for free oar repairs.
If you want, you can retrofit the latest PM5 monitor on every model, even including the A, and use it on Zwift and friends.
(I have a C2 from '96, and it still goes just like the new one in the gym)
