New nonprofit for research on OSS just launched! https://stewardshiplab.org/ From long-time sustainers Mike McQuaid, Andrew Nesbitt, Dawn Foster, Vlad-Stefan Harbuz, Miranda Heath, and Daniel Roe and Patak from npmx. Worth keeping an eye on (and funding?!)
We coincided the launch with a podcast about it.
