How is IPFS better? To share a piece of content, you need some place to share a new link, just like with this mechanism. In fact, IPFS is more failure-prone, because besides removing the link from where it's posted, attackers can also try to identify and DDOS the nodes hosting the content, thereby making the links useless. With this mechanism, anyone with the link could decode the data using some offline tool/script, even if the whole Internet goes down.
