Yes, what stands out with BSS is the degree of integration with R.
"By contrast, pipes, sockets and command-line arguments are communication
mechanisms normally used between two separate programs. So when they are
used for communication, the modules normally are separate programs. But if
the semantics of the communication are intimate enough, exchanging complex
internal data structures, that too could be a basis to consider the two
parts as combined into a larger program."
... and them not providing any source code.
It seems to me to be a violation of the GPL, but i appreciate that is a
"courts decide" question.
There's nothing I can do about it, not being a copyright holder of any R
code, but I post here in case someone here wants to take a look. There's
pros and cons to pursuing GPL violations -- with one pro being that
everyone benefits from the release of additional GPL code.
