This is not just a re-branding, the new global crypto backed by Facebook will not look at all like LIBRA was intended, but more like a digital dollar stablecoin. Facebook is known for trying many things and succeeding only in a few, so it will be something to follow closely. Regulations are probably a major obstacle.

The Diem Association is aiming to launch a pilot with a single stablecoin pegged to the U.S. dollar in 2021, according to a person familiar with the matter.
Formerly known as Libra, the Facebook-backed digital currency project faced strong opposition from regulators and lost several key backers and executives.
At the same time, Diem has gone through a complete makeover and is now in talks with Swiss financial regulators to secure a payment license.
