The underlying blockchains often do not have central authority; that is, no one entity can make a rash decision for bitcoin tomorrow.
Cryptokitties can manipulate their contract, so in that case it is true a central authority is in control. Even though Bitcoin has been around 10 years there is still a lot of development and people are still figuring out how to approach this type of thing. The obvious answer is to start with a central contract and have a mechanism to slowly decentralize or remove ownership. It’s going to take time to get it right but it will happen (and even cryptokitties can upgrade their contract to include this logic).
