Didn't read all the responses, but a short "blip" or even two is a good way to get oil to the motor quickly. I say not more than 2K RPMs and a very short time, then let it warm up a minute or so, and even then, don't blast the throttle, for another 5 minutes or so.
To answer your question, It sounds like hes not hurting it, but kinda needs to repent!!

Blipping while downshifting to make the shift smoother is *exactly* the right and good thing to do. It makes things supremely easier on the trannie and the drive chain and belt, not to mention easier on the rider and passenger if there is one.

The argument about cold engine needs lube makes no sense. The oil pump is driven by the crank, right? The faster it turns the quicker the oil gets to the top and sumps out of the bottom. Reving an engine when cold without lubrication would cause clatter in the lifters, no? I never hear clatter in my lifters on startup (or ever for that matter).
Is it unnecessary? Is it annoying? Those are different questions. She asked if it would be bad for the engine. I see no evidence it is bad for the engine.

This would be a good thread to refer back to when anyone here puts a bike for sale in the classifieds. A person's honest answer one way or the other is more important than "never seen rain". A polished, beat up, low mile turd is worth less than a bike with paint nicks, worn out tires and more miles if it was cared for my someone who knew something about motorcycles.

I watched an s&s video about using chevy lifters in harleys(dont do it) but it showed it lakes at least 1minute to get oil to your top end even with s&s premium lifters. I usually let mine idle for a minute or so b4 I even hit the road. Its a s&s video online. Chris

She asked a simple question, is it bad for a cold motor to be revved? That's all she asked and received some thoughtful responses. The first couple of sentences just established how much he is revving.
Lauren, my guess is it's a habit from days gone by. I've ridden with a lot of people over the years and lots of guys blip the throttle. I remember back in the 60's and 70's when I first started on dirt bikes we always blipped the throttle after starting. I think it was so it wouldn't stall. With all of the electronics these days I don't think that is necessary. Someone mentioned placing your hands over your ears as a gesture of how loud it is. That's a pretty good idea, I think.

Is not complaining about someone else whining?
It would seem to me the more direct approach without the passive aggressive crap would be the best course of action.
The clown act hands over ears or other antics is just so modern nowadays along with cry closets and safe circles.
