By the same token, one could say if you want a white patched long coat dog, get a shih tzu. Or if you want a long coat golden or chocolate dog, get a lhasa apso. Why mess with the standard and have these mismarked dogs, worse yet, breed them, since they're not a part of the standard?
If one type of breeder of OFF STANDARD dogs is going to be accepted/tolerated, because aside from NOT breeding to ONE part of the standard (the color) they are doing just about everything right, then anyone saying that someone that breeds larger sized yorkies who also does everything right is somehow a bad breeder is being a hypocrite.

And let me remind you, allowing larger sized yorkies to breed is NOT messing with genetics, nor is it hurting the dogs. In fact, breeding for abnormally small animals is more problematic for the breed as a whole and for the dogs as individuals, as SMALLER dogs have a greater propensity for things like liver shunt, and luxating patellas.
The greater incidence of these issues in toy dogs is because of us breeding for abnormally small dogs. I'm not sure if anyone realizes this, but toy dogs are in part pituitary dwarves, that we have created. We have bred these dogs to NOT grow any more than a certain size range.
Study Reveals Why Some Dogs Are So Small | LiveScience
"This breed of dogs has a remarkable three-fold range in size, from 25 to 75 pounds. By analyzing the dogs’ DNA, the researchers found the piece of their genetic material that strongly correlated with their size.
The DNA snippet isn’t actually a gene—it’s called a regulatory sequence. This sequence is next to a gene that regulates a growth-inducing protein hormone that helps humans and other mammals grow from birth to adolescence.
In small dogs, one or more mutations in the regulatory sequence suppress the gene’s activity, so it won’t produce as much of the hormone, Lark said, effectively preventing any Labrador-sized Chihuahuas.
In all of the small breeds, the same regulatory sequence was found.
“All dogs under 20 pounds have this—all of them,” Lark said. “That’s extraordinary.”

So sorry, I'm not going to buy that allowing larger yorkies to breed is somehow dangerous and messing with genetics when the genes are already there and are actually more beneficial to the dog than the genes breeders are deliberately breeding for.
Besides, THAT is what breeders do. They "mess with genetics." THAT is how the yorkie was created in the first place.
