But there is also a paid version. Send me $1000 and I will send you R on a USB stick, complete with all the source code. Seriously, other companies do supply support and extensions for R at a cost, and although I can legally sell you a copy of R for $1000 nobody bothers charging for R because the license can't stop you giving your copy away. As for your security/data safety question, well your operating system is probably the weaker link in that chain. However if you are running R in a client-server fashion then you should make sure the data is encrypted - and then the weakest link is possession of the private half of the encryption key, which is your responsibility.
