Decentralisation includes, but is not limited to, cryptocurrency. There are a lot of decentralisation technologies that are potentially quite a lot more useful to deploy, if they really want to. If they put in a torrent or IPFS client, for example, combined with LTE D2D or wireless peer-to-peer mode communication, and made a few tweaks to the app update mechanism, then nearby phones could share updates - saving the user the billable network traffic.
