Earlier quoted context omitted.
The Ethereum smart contract can advertise the file in perpetuity by being memorialized on the blockchain in an irrevocable way
You'd have to embed the whole file in the blockchain for that. At that point Filecoin is not relevant. That's not censorship-free either - the use of Eth network can be banned too. And LE or govs see who to target too.
No, you don't. The eth contact can control ownership of and permissions to the Filecoin files.
> Eth network can be banned too
Banning the entire network is different than granular censorship of individual files
> And LE or govs see who to target too.
Anonymity is also different from censorship.
You are talking about a lot of adjacencies and "what-abouts"... There are at least half a dozen projects in this vein at the moment, so I'll kindly leave the rest as an exercise to the reader
