"Free sharing": in what sense? 

Undoubtedly, to your main point. 

My guess, however, is that SAS were never going to get you to buy 
their complete manuals in printed form. 
The revenue foregone is zero, in that respect. 

Whereas how much are you paying for SAS? How much is your 
institution paying for SAS? 

As I understand it, the Stata and SAS financial models are 
very different.

I know about Stata. I know next to nothing about SAS, 
so I speak in ignorance. 

As reminders, however, Stata give you

* technical support on current and previous versions 
(if registered) 
* free upgrades between releases 
* indefinite rights once you have a licence (no 
annual fees) 

Stata charge you 

* for buying a copy (once only) 
* for upgrading a copy (as desired) 
* for the manuals (each release, potentially, 
although some skip a release or do not stay 

If SAS, or indeed any other statistical 
software, has a similar pattern, then we
can compare like with like. 

Otherwise, the only fair comparisons must 
take into consideration the total picture 
of what is free (not charged for) and what
is charged for.
