Personally, I would say Richard Stallman has respect for open source software: https://www.gnu.org/philosophy/selling.html.

Having respect for free (as in "libre") software means caring if the software can sustain its own development, and not just caring if you get it free (as in "gratis"). It's not always viable to support a project on donations and free time the way GNU is. https://xkcd.com/2347/
