I have been using the same open source typeface for programming since I found it many, many years ago. The industry reminds me of music licensing, there are so many free choices that are public domain, but if you have the money you flex and spend it on something custom, even if it is more or less the same as the free option, because that distinction is made by the end users. It reminds me of 'It's Always Sunny in Philadelphia' using public domain music for many of the scenes and the theme, and now I hear that tune in many TV shows.
