If you distribute R to clients, you will need to make R's source code available to them in some manner along with any modifications to that same code, while preserving appropriate copyrights.

However, since their products are founded upon the official R distribution and the GPL, they will have similar issues with respect to any enhancements that they have created and therefore, your concerns do not necessarily go away. They will have also consulted legal counsel on these issues because the viability of their business depends upon it.

I agree with all of that but for one thing:  not all distributions are 
built on the GPL'd original.  I believe Tibco is selling an independent 
implementation.
