Hawking radiation is a quantum phenomenon. The idea is that you can have a particle-antiparticle pair occur very close to the horizon of the hole. The antiparticle then falls into the hole, decreasing the hole's mass by a little and the other particle then flies away which is the radiation that is measured. (Don't ask me why it is the antiparticle going down the hole. There's some sort of thermodynamic process going on there.)Quite form Physics.org

"The most massive black holes in the Universe, the supermassive black holes with millions of times the math of the Sun will have a temperature of 1.4 x 10-14 Kelvin. That's low. Almost absolute zero, but not quite."

So, yes, the black hole will radiate energy in terms of an outflux of particles which gives it a "temperature."

The particle-antipartical pair are on the limits of that. One goes in, one escapes. The escaped particle is what tells you the "temperature."nolight to escape because of the temperature. That gravity is holding light back is a widely held yet incorrect concept.

I'm not clear on what you are referring to. "the notion that "light" (as photons or waves) cannot escape a black hole because of the enormous gravity is specious." The horizon of the hole (defined to be at the Schwartzchild radius) is the limit where the escape speed from the hole is the speed of light. What exactly are you saying is wrong?
