anyone with experience about Radicle, could it work for the DAO to own code ?
any alternative ? feedback ?
The code used by the DAO is already open-source on Github 
Github is centralized, the DAO cannot own repositories there, other entities/persons are needed to act as bridges.
Neither of these statements are true. Basic research contradicts the first two.
The last one is only true in so far as the DAO not having the expertise of doing it themselves…
Which they will have to acquire at some point, before the mandate from the Foundation itself expires.
