Well, SCION might not be open. No open standard, no IETF, no open source implementation, and its single commercial exploiter has patents on the technology: https://www.anapaya.net/news/path-selection-system-patent?hs...
They want to sell a technically brillant protocol that is single vendor propriety/patent restricted.
Their bet should have been of open protocol and captalizing on fist mover advantage to drive their business side witha large partner like ericsson/cisco etc.
Of course theres also the soveriegnity angle knowing what went on with another swiss company CryptoAG.
And that patent looks like it is for an optimization, not a necessary component of SCiON.
