> Does this hurt FOSS contributions, because now people start to expect to be paid rather than doing it for inherent motivations? Will this generate toxic politics among project contributors regarding who gets credit + gets paid?

I'd also be concerned about features being implemented because there's money behind it, forgoing more important technical reasons.

Of course there are many projects that already implement this 'quid pro quo' development strategy, and open source projects with big corporate backers. How do these projects currently handle monetary influence in their decision making?
