NI already have inhouse versions of many of their software tools for Linux, and they use it in house for some development. I met with them in person several years ago when I was teaching in Berlin. They are quite big technical fans of JACK and of Linux, but they (probably correctly) see a tiny, largely irrelevant market for native releases for these platforms. They spent quite a bit of effort to get their standalone versions on OS X to talk to JACK if it is installed, but chose not to document this because hardly anyone wants it and when they do, they figure it out for themselves.

A lot of people (even on this list) don't understand the extent to which *supporting* a piece of software is often a far bigger cost than the initial development, and providing support for a platform with very few users is an issue for companies who want their customer service reputation to be very good (as NI does). It doesn't work for companies like this to just release something "into the wild" and forget about it.
