A positive spin would be this: Eovia wants to reward those who don't just use Carrara, but have also joined the active Carrara community. Regular Carrara users don't get the discounts, but the really "involved" users do. If you look at it that way, Eovia is rewarding their best customers. The ones who have not just helped their bottom line, but who also endorse the product and show off its capabilities to the broader 3D community.
