Actually there is. The Ripple fiasco arised because the creator (jed) owned a large amount of XRP, and decided to sell large quantities of it, hence crashing the market. In hyperledger, organisations can issue their own assets, therefore can own a large quantity, therefore can crash the market by selling a lot.
Hyperledger as a platform is technically independent of and will survive such market crashes, but this is kind of irrelevant since the currencies/assets it enables the creation of are exactly vulnerable to all the same flaws that XRP is vulnerable to. Ultimately the users of hyperledger don't care about the platform, but care about the value, fungibility, liquidity of the currencies/assets.
Furthermore, it seems to me hyperledger is not decentralized at all. IIUC the issuance of the currencies/assets is 100% controlled by the rules defined by the organisations that created these currencies/assets, so who would guarantee me for example that organisation X is not going to issue 100 billion more units of currency Y tomorrow?
