@nicksellen the way you asked the question implies there are specific things that are causing concern.
The answer can be anything from "single git commit is all" to "never legally possible" and it depends on a few factors (number/contactability/agreeability of authors being a major one).
@Greg two separate cases actually:
with https://github.com/yunity/karrot-frontend we *might* be able to contact the authors, although now I look at the list, maybe not... lots of 1-time small contributors..
with https://github.com/FediHospEx/federated-trustroots it's a fork of an MIT project, and could likely not contact all authors. would also like to be able to pull (MIT) changes from upstream.
as MIT is so permissive, I thought they might be options to just change it to AGPL, but maybe need to keep some reference to MIT too....
