Exactly. Later there will be deletable chunks, but there is a lot to consider, especially security and privacy with that.
If data can be traced to you then it can be deleted (we are working on a method where it cannot be traced to you, but it is very complex and not for right now), if that makes sense. So we don’t want to do that.
There is a mechanism now where you can create throw away id’s to publish data anonymously, so great, but it cannot be deleted. Public data cannot be deleted, You will in the future have private data you can delete. I think of data as a thought, if you share it then it cannot be unshared, or forgotten, at least by force. So the network works like that.
