What do you mean it's decentralised? It's a central service you have to query for name->IP lookup, with authoritative name servers for every domain. It's the very definition of centralised. Just because it's hierarchical doesn't mean it's not centralised. A decentralised DNS system would be more like a p2p network where you can perform name lookups from any participant in the system. Companies aren't trying to do anything weird with DNS. It's just how most things work in service architectures. Every network query will start with a DNS query. You might depend on 50 services, with circuit breakers and all kinds of great logic so a single service won't bring you down - but there is that DNS lookup which will break everything if it fails.
