That is exactly what a brand is supposed to protect you against: if a reputable brand is caught doing this, it won't take long for its reputation to go down the drain.
You won't see many reputable brands engage in this, and that also explains why they rightfully complain when someone else uses their brand to push their bogus products, as their reputation can take a hit due to a malicious player.
Intellectual Property protection around brands (brand names, logos, etc...) is serious business.
