The general public varies on this to a degree that makes it difficult to draw any, well, generalities. I've had people say my mutts are adorable, sweet, "too pretty to be a rescue" (Kim), well behaved, skittish (also Kim), and likely to turn in me one day and kill me in my sleep because that's what rescues do.
I have also had them insinuate that my purebreds are a waste of money, ill-gotten, gorgeous, brilliant, the direct reason a rescue dog was killed, and had dollar signs pop into their eyes as they inquire how much I can charge for all the puppies I am surely making with them.
There are bad breeders. There are rescues just as bad. There are good breeders and there are good rescues. Some (of both) go above and beyond, some just do what they need to and wish you well and move on.
So no, I don't feel badly about purchasing my two purpose bred dogs. I don't feel bad about my fish store purchased dog. I don't feel bad about my private foster Petfinder dog or my cat purchased from the Humane Society.
Kim and Brie made room for other animals to be saved, and that's a good thing. Mira and Lodin helped to not bankrupt people trying to breed good dogs and have their health and other information available to help with future breeding decisions for the lines and breeds from which they come. And Webster is out of a crappy situation, didn't end up in the shelter that puts dogs down for resource guarding, and didn't result in a profit for the fish store so I'm calling that a win too.
