Except ipfs content disappears if no one is pinning it. And you can find IPs of hosts which are pinning it. Yes there is FileCoin but there are minimum and maximum file size and contract duration limits. So someone has to periodically check pins, contracts and keep purchasing new FileCoin contracts to keep it online.

Yes, true, I don't think ipfs is meant to be censorship-resistant though, so finding the IP of hosts doesn't seem like a big deal for the project goals.

My point was more that the NFT metadata itself could still be usable x years in the future when another protocol has replaced ipfs – it would just have to make the files findable by the existing hash.

The biggest potential risk would be if sha256 becomes broken and finding collisions is trivial.
