I could be incorrect, but my understanding is that the DHT used to route through IPFS is not robust to attack. A bunch of nodes could join the DHT and start maliciously routing data in circles, and that would be a very low cost way to significantly disrupt data availability and uptime on IPFS.

A few papers exist that describe byzantine fault tolerant DHTs, but they make assumptions about the percentage of evil nodes, which requires some method of authentication / Sybil resistance to be effective. Also the network cost blows up substantially, and DHTs already aren't very fast in terms of loading things like web pages.

It is not censorship proof but it is resistant to censorship.

A state actor would need to block all IPFS hosts as soon as they begin to serve a specific CID. This is a game of whack-a-mole that would be difficult to maintain.

It will get cheaper to "save" but more expensive to access
