I would ask contributors to this list to at least note that the sort of FUD (Fear Uncertainty and Doubt) of the type mentioned by the poster is hearsay. Do we have any contractual promises from SAS Inc. or other companies that they will guarantee their software? Have there been documented compensation payments? If so, then that is information that should be provided, rather than "someone said to someone and they told their dog and he barked to me that ...." Perhaps someone from Revolution can comment (and maybe provide documentation) if they provide a warranty or insurance for their implementation of R. Warranties and insurance for open source are not unknown: http://www.computerweekly.com/feature/How-to-use-open-source-with-confidence http://news.cnet.com/2100-7344_3-5143326.html Another aspect to this hearsay issue is the pricing for commercial software. I happened to see the invoice for SAS for a single, albeit powerful, laptop that was about $90,000 per year. But I have yet to find a published price list for SAS, nor for many commercial packages, and I cannot document what I saw. At least I can give you the price of R, though I always am careful to tell potential users that it is not without cost -- you really do have to join the community if you want to be a true R user. This is not a gripe about SAS or other commercial software vendors, whose pricing and service strategies are rightly their own choice, even if we dislike them. It is a commentary that we, who work in the Free/Libre software should not assist those strategies by promoting unsubstantiated opinions that work against us. Given how email works, the poster may in fact disagree with the opinion he communicated, and was trying to alert the community to such views. I just want to note that, as a community, we need to be alert not to accept FUD for fact.
