It is sometimes very irritating that a very free/open community like the amateur radio community mostly wrote non-free software for Windows in the past few decades (and to some extend still do). Take most of the well known analog filter design tools - they are all .EXE files.
The well-known author of EMRFD book shipped the CD with some very useful software, all binary programs. Someone wrote to him saying that an antivirus software was flagging one of them wrongly, so he took down that program instead of releasing the source code! Today, I was looking at an old paper on crystal filter design which referred to a software whose cost increased to $150 after a favourable review on QST. The author is long dead and with him, the software binaries too!
