Passion =/= Competence

On the margin, there may be many people working in, for example, finance who would make highly valuable contributions to open source projects if they were financially incentivized.

What is effectively being argued here is that we should oppose grass roots subsidy of important public work just because there was a specific incentive issue in a specific initiative. The code doesn't care why you wrote it. Maybe some bad code gets subsidized. That's ok - don't use it.
