My (and other people’s) understanding of this item is that you should be able to build your own ROM on your computer (which is still borderline not the case given the “only on a Fairphone 2 device” clause) with it, but can’t share it (since the license is non-sublicenseable and non-transferable). I’ve had confirmation from @keesj that this is restricted here two weeks ago, along with the promise that they are working on a way to circumvent this issue.
We have had no news of this since, as far as I know.
