I should probably add: if it becomes proprietary, the remaining soft fork will likely die. Turns out very few people have the technical knowledge for Audacity.
If you want to read the telemetry controversy/drama, I found this one I’d read years ago: https://github.com/audacity/audacity/pull/835
I remember feeling a bit bad for the maintainers. There’s a lot of complaining for a minor and optional change, but at the same time it’s interesting that they added telemetry anyway. (Not unmodified however)





As far as I’m aware, contributor license agreements can include a clause stating that you agree to hand over copyright on submission of code. If every contributor has signed the CLA, there is only only one copyright holder, making relicensing easy.
However, successfully using this to relicense to something less open is extremely rare, and this isn’t a concern anyway as they don’t have a CLA.
