I mean like I said, that does suck. But we do have other options in the interim, namely Soyuz and Cygnus. If Boeing had decided to actually try to fulfill the commercial launch providers program there would also be starliner...

There are also a lot more options just around the corner, there's the dreamchaser which looks totally badass, also JAXA is working on a vehicle and I read that the ESA is maybe working on 3 different vehicles?

Remember, by decommissioning dragon, all they're really doing is removing the cheapest option from the market, and that's the only reason anyone cares. The other options that have been available are still available.
