Anyone can write an article, it's their opinion; their article can be biased or unbiased. I try to look at all sides of a story but tend to go by what the scientists say and by what the people who own or breed these colors have experienced. Just punch in "canine color genetics" if you want to learn about the chocolate color, you'll find 100's of articles on canine color genetics. You'll be looking for information on the "b" locus series of genes when researching the chocolate color.
Below are a few articles for your review:

As for the blue born yorkies, they normally have a condition called color dilution alopecia.
