I understand that Libra coin is "centralized", but so is XRP...How can you love XRP, but hate Libra coin?
Why don't you asked the people who strongly supports XRP? Many people do not like libra and xrp.
Granted, I don't support or like FB, but this is a giant step towards mainstream adoption.
I think you are assuming too much that those people behind libra are thinking of crypto mainstream adoption. They are only thinking of libra adoption.
