This is for public data. Think Twitter posts, StackOverflow answers, Reddit comments, etc. The stuff you don’t want companies to gradually start locking up for their own gains (as they tend to). The protocol will likely be extended for private and semi-private data in the future, which would work by granting explicit permissions to apps. For now, app developers would keep private data in databases, same as usual.
