Artsy software will always thrive as closed source. The types of companies that actually need and use Adobe/3DS/etc. are too damn loaded. Meanwhile all the software that never makes anyone any money is abundantly free and open source (Haskell, web browsers, Linux and such).
If the phrase "Follow the money" can be applied to finding exemplary use cases of proprietary software, then the corresponding phrase for open source is "Follow the poverty".
