There's plenty of middle ground. Lots of people--the majority, I'd say--treat open source as a positive and seek it out. But they also won't go with an inferior solution just to check the OSS purity box.
I would agree with this. Personally I've tried to choose companies whose products are fully free/libre, and for the most part have had success with that. I am no RMS, but I have a strong preference for open solutions. Because of that my sample set is certainly biased toward others who at least feel the same.
