MobilityData projects including their CC0 transit software list require contributors to sign a CLA which includes giving away your mailing address and telephone number. Which is bizarre to me as this is literally just a list but they wanted me to even sign a CLA for that?
Before I even read your post I already made a fork of the list with my changes.
(and removed anything I thought was not “FOSS”)
Anyone can take a look at it here: Pi-Cla/delightful-transit: A curated list of delightful FOSS transit APIs, apps, datasets, research, and software - Codeberg.org
