Well foo, I was misread and thought there was some tamaskan anyway. I really like the temperaments of those dogs.
Regardless, tamaskans and utonagans have both been around for a while now with very similar goals as this breeder, and there hasn't been a giant backyard boom of bybers trying to cash in. If people want the real thing, there will be a registry and they can make sure they're getting stuff from the original lines that way.
If people want to be cheap and lazy, and buy mixed breeds out of the newspaper they'll do that regardless. They do that even with purebreds, does that mean nobody should breed aussies because bybers sell aussie mixes as purebred? I don't see how that should stop anyone from responsibly creating a new breed.
And lots of people don't want sibes and hybrids, but like that northern breed look (like me). Rather than water down existing breeds to fill a companion niche or continue producing hybrids that most people shouldn't own, isn't it better to create a new companion breed?
