with the exception of privacy coins most of it is not good for anonymity/privacy by default (a wallet address is effectively a public psuedonym with a social graph), but that has no bearing on the decentralization of crypto protocols, which ranges from fraudulent to extremely strong, depending on the project. there are ways to use bitcoin with very good privacy, like chaumian coinjoin, but they are not the default behavior of the protocol. nobody describes bitcoin as anonymous besides local news anchors and other low-information audiences.
