I work for Posit. We're a PBC, and developing open-source software is quite literally our mission. You can read more here: https://posit.co/about/pbc-report/ (we used to be RStudio, so that's the term you're going to find in that 2021 report)

We're for profit, but here's the relevant paragraph: "Together, RStudio’s open-source software and commercial software form a virtuous cycle: The adoption of open-source data science software at scale in organizations creates demand for RStudio’s commercial software; and the revenue from commercial software, in turn, enables deeper investment in open-source software, which benefits everyone."
