I think you're letting your personal beliefs/circles affect your view on the FOSS ideology. Free software has nothing to say for or against commercial software. Commercial software doesn't need to be proprietary. I was there in the late 90s and early 2000s too and it was a minority (of proponents, many opponents would slander FOSS as a form of socialism) that somehow equated open software with socialism.

We're talking free as in libre here, not free as in beer.
