Yeah, it's not right. But I'm strong-headed and well-researched enough to bat that stuff away, so I don't count myself as some sort of victim in it, but there are certainly others who could be more easily hoodwinked.
Anyway, I'm sure if you tried to do anything about it they could easily come up with a list of clinical reasons why it was suggested to cover their arses. And I myself can't prove that this wasn't the motivation... but yeah, pretty clear they were just hoping to offload expiring stock at inflated prices.
