Google sponsors a lot of open source work: https://opensource.google/organizations-we-support

I wonder if sudo would be better off joining one of those open source foundations instead of staying solo. It's too small to justify a meaningful amount of contribution to these companies, at which point the bureaucratic overhead of dealing with it probably kills the motivation

This is the current list but from a cursory look it lacks GSoC which has been a significant source of new contributors since forever.
