Not when you live in Palo Alto! So you get an idea of what it's like here. If where you live isn't particularly fancy, it'll be an even more accurate experience.
I've always found academic research to be one of the most natural homes for open source software. It's in the paper formatting software (latex) and much of the lab software.
There is a broader statement: open source is fueling the future. In fact, holding off projects close sourced only makes it profitable for one-party for a while, until an open version spins off. Open source copies are bound to happen.
Alternate theory: open source is destroying the future. In fact, significant progress is occurring from concentrated capital investments made by public entities or corporations, and development slows down or regresses once open source alternatives become available. The likelihood of open source piracy occurring decreases the overall desire for coordinated, large scale technology development.
The article mmentions Moose, MFEM, OpenMC, but the really good stuff relevant for us nuclear physicist I would expect being talked about aren't mentioned: Bison, Transuranus, Marmot, Serpent, Vasp, Rattlesnake, Fispact.
On the open source open access side I'm missing Lammps or Geant4.
Moose & MFEM are great projects and important in itself, but not relevant in the nuclear physics ___domain. Software which is remains export-restricted for good reasons. Here a list for the curious mind:
My first job as a programmer, in the early 1990s, was working on a tool that was used in one of the last US underground nuclear tests. It was a finite-element electromagnetic effects simulator, designed to help get off of actual bombs blowing up and on to simulation to help design for radiation and EM effects on military equipment.
My part was a 2.5d viewer that showed the input model and let you rotate it around and zoom in and out and such. We used X386 (the predecessor of XFree86), the Athena widgets, and GNU tools on a commercial SysV Unix for PC hardware. This was the era of the actual 386; maybe Linux existed but it was well pre 1.0 (I know because I started installing Linux in the 0.99 kernel days, and that was 3 or so years later)
Open source has been fueling the future of every single technical endeavor for 30+ (40+? more?) years.
