It's not nonsense, what is nonsense is a pilot suggesting that the correct way to recover from a stall warning in a commercial jet is to release the back pressure.
You reduce the AoA by moving the stick forward as per Boeing and Airbus QRH, anything else is unacceptable. Both QRH's also refer to the possibility that you may need to reduce power and trim the THS forward in order to gain enough elevator authority if moving the stick alone is ineffective.
Depending on the aircrafts trim you could be holding a high stick load, none or anything in between its even feasible, especially with electric/auto trim, that you could be trimmed fully nose up. If your holding lots of stick force then maybe releasing the pressure will remove the warning, no guarantee, but that response will reduce the closer to in trim the aircraft is and that is why saying "release the back pressure" is wrong and dangerous.
As for pulling to the shake sticker on a base turn! What aircraft and operation are you referring to that would advocate releasing any back pressure is an adequate response?
