[Rd] Blue Sky Statistics - GPL Violation?

[Tom Woolman]

Hi. I am not a lawyer and I didn't stay at a Holiday Inn last night, but 
I don't think this is a GPL violation. The closest analogy for non-GPL 
release packages that comes to mind is with h2o. h2o is proprietary (for 
profit) that is also simultaneously released on CRAN; their business 
model is consulting services for selling support and app development for 
h2o-enabled models, but they allow free use of the core algorithm 
without paying a license fee.

I'm a huge fan of h2o and have used their GBM and MLP algorithms to 
build models for my two most recent published papers (in press). I 
suspect that this type of hybrid freeware/retained rights framework 
might be the future for some of the larger, more scalable and robust 
library package releases. It seems to also mitigate somewhat the issue 
of abandonware packages, because people are throwing some bucks into the 
tip jar via enterprise support license subscriptions.

Which reminds me that RStudio also does something similar :)
