I think the point was that if an aspirational minimum wage worker on a borrowed computer wants to put up a PR then it would cost them less than ten minutes of wages to afford $1USD in the US, while the same worker in India would need to put up about half a day's wages.

This is very noble in theory, but in practice you're not going to get many high-quality PRs from someone who's never been paid to write software and has no financial support.
