How is it that web apps are supposed to be open and apps are supposed to be proprietary, as though Microsoft OneDrive is "open" and IPFS is "proprietary"?
OneDrive having a web client doesn't make it open. If you think about OD as just a way to access and share files then it's probably open since the web client will run in any modern browser. However if you think of OD as a platform of sorts then I wouldn't consider it open since, to my knowledge, MSFT controls everything about it and it's not standardized.
