Yes. You should complain if you buy a new car and it doesn't come with a full tank of gas, or needs new tires, or needs an oil change right from the dealership. Those are things you expect from a new car, and they're the reasons you buy a new car.
If I bought a used knife, I'd expect to sharpen it. If I buy a brand new knife, I expect it to be sharp right from the factory. If it's not, I could have saved money and just bought a steel rod and made my own knife out of it. A knife has one purpose: to be sharp. If it's not, it's not a knife. It's a cheap hunk of thin steel that they told you was a knife.
There is zero reason a brand new product needs immediate maintenance before it can be used.
Those are thing you expect from a new car, and they most certainly are not the reason I would buy a new car.

You might expect that, but the practical reality is that knives don't really come truly pre-sharpened, and there are many reasons for that. People don't realise that this is the case, because most people, in general, have really, really dull knives, so even a mediocre edge will seem comparatively sharp. But it isn't, it's just mediocre and once you have used a really sharp knife the difference becomes very apparent.
There isn't one way to sharpen a knife. Some people prefer an asymmetric edge, some people hate asymmetric edges. Some people prefer shallow angles, some people prefer steep angles. Some people prefer knives sharped for slashing, some people prefer knives sharpened for slicing. There is no right way to sharpen a knife, it is something extremely user-specific and personal and there cannot be a way to pre-sharpen them that would satisfy all people.
Because it is such a personal issue, I fully expect that I need to sharpen a new knife the way I want it, just as I fully expect I need to installs the apps I want and configure a new phone before I can use it.

This is just hyperbole.

And yet many products are like that. For example DSLR cameras come without SD/CF cards. The user has to buy them and put them in the camera before he can use it.
However, that price point is the bottom of the bottom of the lowest end when it comes to knives and should be reviewed as such.
I mean, a BMW may be a high quality car, but most people are going to just get a base model Toyota Corolla and they're just fine with that choice. I can buy a kit car that makes me supply my own engine and tires and exhaust and electrics and it will be custom fit to my exact needs, but for the Toyota Corolla owners, they want to buy a car that already has all of those things and can be driven off the lot.
I'm not criticizing your choices, you seem very knowledgable. I'm just trying to help you understand that when you say "a knife shouldn't come sharp from the factory" and "that $45 knife is the bottom of the lowest end", it makes you seem incredibly out of touch with how most people buy knives.
If I bought a knife that wasn't sharp, I would return it to the store and get a different one.

Knives are meant to me sharpened. The cheapest knife can be sharpened to razor blade sharpness. Sometimes new knives come sharpened somewhat, but in my experience all mass-produced knives need sharpening when new, even $250 knives.
I genuinely can't comprehend the complaint. What next, buy a new car and complain it didn't come with the tank full?
