You don't need to explain anymore. You've done enough. You've made the separation clear.
Although Ripple’s marketing material refers to the blockchain it does not use blockchain technology, rather its own version of a distributed ledger protocol, ILP. Ripple’s value add is its the only open source decentralized payment system that complies with the global banking systems regulations, privacy and need for transaction processing speed.
The company defines it this way: “Ripple’s solution is built around an open, neutral protocol (Interledger Protocol or ILP) to power payments across different ledgers and networks globally. It offers a cryptographically secure end-to-end payment flow with transaction immutability and information redundancy. Architected to fit within a bank’s existing infrastructure, Ripple is designed to comply with risk, privacy and compliance requirements.”

The problem I think people have besides the fact they've invested into it is, it seems that Ripple is being wishy washy with XRP. One minute it seems they going all out, the next it seems like it's on the back burner.
