Advertising "open core" software

[Rahul Sundaram]

Hi,

Open core, for those not familiar with the term is the business model of
keeping some key features closed and selling a proprietary product where
the "core" functionality is free and open source.  Two features in the
feature list are such software

Zarafa groupware and IntelliJ IDEA, IDE for Java have a number of
features that is only available in their proprietary product.

Do we care?  I am concerned about this.
