That's a very interesting question and I'm not really sure what the answer is in general but I can answer for myself.
I'm an EE. I can code. I think I'm pretty good at it. But there's a reason I didn't major in CS, I don't enjoy it all that much and I don't do it as a hobby either.
If you believe that those who contribute to FOSS is a small percentage, then I think for non-SW folks you're looking at a small percentage of a small percentage, which means sparingly few contributors which means sparingly few FOSS EDA tools.
