I still don't understand why the amateur radio community has this disdain for open source. It feels like a majority of the popular amateur radio software tools out there are closed source freeware projects.
The amateur radio community isn't enormous, and the overlap between operator and developer doesn't always exist.
That said some of the most popular ham software (like WSJT-X) are open source. I think the trend is starting to shift the other direction.
