To be honest, I can only say agree with the statement above, it is not important between centralized or decentralized. As long as the service provided satisfies customers in the sense of being fast, cheap, transparent, and having a good team. But most crypto lovers don't like ripple, especially my Facebook friends who sometimes share articles that deflate xrp. But as long as there is decentralized that can compete with ripple, why not.
You're right about people in the crypto community not liking any project that's centralized but there are something we must not ignore (centralization, fake volume listing, scam project either ICO, IEO, ROI investment etc.) for the future stake of the cryptocurrency. However, statement which was said by the MoneyGram CEO was just a statement used to praise the person that saved his company from quenching.
XRP is a crypto that will satisfy customers but scam them.
