Good for her - I hope she will go to a family that will appreciate her and love her not breed her. But why do people buy from these kind of people??? Because it is easy and they can get breeding rights GAG!
If you can explain how to tell someone who talks a bunch but doesn't know what they're talking about, from someone who speaks knowledgeably about their dogs because they know what they're doing, and do so in terms that don't require reasonably advanced knowledge that can take months or years to acquire, then you can say they have no excuse from buying from someone. Folks' attention spans are generally short too, so the explanation has to be concise.
You've pointed-out a few things from this breeder's website that you see as red flags, but much of it is subtle. I could see how someone with a particular price range and aspiration for "good bloodline" could look at your website, look at eurodoby.com, and miss the more subtle warning signs & think both you and the Pilipovskis are similar. I mean, you both talk about health testing buzzwords (even though the specifics are different), you both talk about nice-sounding bloodline things, and you both have dazzling photos with awards poses. Someone who doesn't ask exactly the right questions or catch the nuance is going to struggle to make a good decision, because price does not influence quality, only vice versa (and not always).
It doesn't come down to control-freakishness, either. Anyone can talk about how they screen prospective buyers, but it doesn't mean a whole lot. If someone wants breeding stock to keep their future options open, but you refuse to sell to them on that reason alone, congratulations, they're just going to go elsewhere, and you then have no influence to steer them in a sensible direction even though you'd also avoid facilitating bad behavior. It's still hard to blame someone for refusing to take part in a situation that feels like it's going in the wrong direction in the first place, but the small cost is likely going to be that they might wind-up doing even more damage due to a complete lack of guidance. I believe that's what's called a no-win situation.
Also, it's hard to tell until you've been burned, that you've been burned. How do you know someone is not giving you the full truth until you catch them in a story that just doesn't add-up or that changes depending on circumstances, unless their story is just unbelievable from the start? You really can't, especially if what they say is mostly plausible, or they're just too incompetent to know they don't know what they're doing, and since they don't understand that, it makes them that much more confident. The Dunning-Kruger Effect is scary territory. In light of the developments, I wonder if that may be what's happening with this breeder.
That's what this comes down to, hopefully the beautiful dogs involved stay healthy enough, maybe you should make a short breeder questionnaire and explain a range of acceptable answers to help folks who are trying their best to screen their breeders better. It's not very helpful to point out the warning signs after they've already committed.
