Is filecoin fully decentralized?

Is there a way to store data in a fully decentralized manner? It seems that every tutorial connects to either a remote or a local Lotus node, but this would mean that filecoin is not fully decentralized. Also, where is a good place to go to get more information on how to build a webapp or dapp using filecoin? Thanks!

No, filecoin is not a network for decentralized storage, it is a decentralized network for single node storage
