I don't really see much wrong with it. Whereas Ripple is certainly a centralized and regulated pro-bank project, what's wrong with Ethereum? Moreover, it's good that people in the administration will be at least favorable to cryptocurrencies at all (and the Ethereum guy can push pro-decentralization, no?). After all, much worse people could be appointed, both from the crypto sphere like Craig Faketoshi and, even worse, some stock manager/Paypal guys who think Bitcoin's a financial pyramid and a thing drug dealers use. While Ripple and Ethereum might get an advantage out of this situation, I think there'll be good stuff for the crypto market in general.
I heard that the team could manipulate Ethereum at some point which makes it a bit dangerous. They have some control over Ethereum and that this is proven from the fact that they have a top models governing the cryptocurrency. I think Ethereum did try to become decentralized but it failed. Ethereum and Ripple are both centralized. Who knows what this guys have in mind since greed will always be there in the corner.
