Here's how I ask for open-source in my mutual aid groups, when they're taking about setting up new digital tools:
I don't have the bandwidth to involve myself in any of the tech stuff, but have a strong personal preference for open-sourced software. Is there a chance either of you are already familiar with <open-source alternative>, so could set it up instead?
Again, FOSS nerds, mutual aid groups need your help. Stay on your ass but close the video games.
