It's only partially open source. Some server-side code remains proprietary, and the client-side will depend on proprietary code of Google and Apple and they do not plan to support platforms that are actually Free Software. The law overall is badly written. For example, articles 12 and 26 effectively say that "The source is shared with public, except if it is proprietary or insecure." Or take Article 4: "The government may operate systems that protect the privacy of the identity subjects."
