If I'm not mistaken, Libra is the name of the blockchain, and Calibra is the name of the company. I see the Facebook team wants to build a Blockchain and coins that have coin capacity levels into global currencies. I think this is not much different from the blockchain that we are currently using. Maybe the Libra name is popular more quickly because it has a Facebook team. For the truth of this we have not found. Perhaps the strength of Libra is that it is easier to recruit investors compared to Bitcoin in the past. Bitcoin is formed from the ground up, whereas Libra has already been there Facebook as a strong foundation.
If Facebook is really building a blockchain, then I think that they are already digging their grave already, except maybe they will regulate the blockchain and any project that will want to come through their chain, because we can see what is happening to Ethereum right now.
Whatever blockchain that Facebook is building will be very similar to the services of Ethereum also and if that is the case, they will surely affect the existence of Ethereum because many people will migrate to their blockchain being that they are very popular already and people will get to know about projects through them than any other blockchain services company but we will still end up having shit projects more through them through the billions of users that they have except maybe they will regulate theirs.
If indeed the Libra Blockchain only copies and pastes from existing projects such as the Ethereum and Bitcoin Blockchain, it means that the use of the Libra Blockchain is not much different from the current one. So, there is nothing superior here. See some new blockchain after Bitcoin and Ehereum. Blockchain is much lower quality than Ethereum and Bitcoin. I think there is something new created by Libra, so that it attracts the interest of small investors. If only those who invest in Libra only popes have millions of dollars. Meaning Libra has no global impact.
