Almost everybody knows the words "open source" draws developers and users, much more than "proprietary/closed source". Adding "completely" in front of "open source" would draw even more users, as would certification from the Free Software Foundation. If it the DragonBox Pyra could be made to run on completely free and open source software, it would draw a lot more attention, would sell more units, and would draw many more developers. Is it a possibility, given the current hardware purchased? I know if open source drivers can't be had, that reverse engineering drivers isn't easy, but it still can and has been done. I think if the software could be made completely free and open source, and I mean completely, then the positive effects on software development, units sold, and the Pyra community in general would be unpredictably greater. Edit: Perhaps even using Coreboot or Libreboot and Linux-Libre with only the necessary proprietary drivers added would still draw more users and developers, if no better option is viable. It certainly wouldn't draw as many though, since it couldn't receive FSF certfication with any closed source code.
