Filecoin, which is based on IPFS, creates a market for unused storage. I think that idea is great but for adoption it needs to be as simple as Dropbox to store files. But visit https://filecoin.io/ and the dropbox-like app that you could be willing to try is nowhere to be found. So maybe it is an enterprise solution? That isn't spelled out either. So I am not surprised that this has little traction and the article further confirms the impression.
