While undoubtedly true, it’s also true that Linux is nowadays the default OS for VFX, for example, and this means that a lot of commercial 3d software targets it (for example, Autodesk Maya or the Substance suite). There is a standard “platform” of reference that allows companies to have a fixed target for their software: https://vfxplatform.com

I think targeting it would be probably the best solution for a company willing to porting to Linux. Alternatively, Flatpaks/Appimages provide a very nice and user friendly solution to this problem.
