Here it's more the other way around. CERN needs a data analysis framework, so CERN develops, maintains and publishes it for other users.
That being said, I don't know whether it's actually a good idea for someone external to actually use it. My experience may be a little outdated, but it's quite clunky and dated. The big advantage of using it for CERN or particle physics stuff is that it's basically a standard, so it's easy to collaborate internally.
