Back on December 1st, it was announced that Diem's supposed release will take place in January. This is due to the fact that last month they should have received permits from the Swiss regulators, where Diem was registered.
However, after a while it was found that one of the companies in England was already using a cryptocurrency called Diem and was ready to defend its right to this brand in court. Since then, nothing has been heard about the release of Diem again. Zuckerberg was out of luck again.
