Lu, I agree with you entirely but I don't see where the contradiction between P&W and RR is. From the RR site;
"...This demonstration shows that the reaction is an internal function and does not, as is often assumed, result from the pressure of the gas stream on the atmosphere.
The reaction to the gas stream which is ejected from the nozzle is felt on the parts of the engine opposite the nozzle, mainly the front of the combustion chamber and the tail cone.
This force, termed thrust, it then transmitted from the engine casing to the airframe, through the engine mountings, to propel the aircraft."
Surely they're both in agreement?
Regards.
