FileCoin is a blockchain and is the incentivization layer on top of IPFS that allows users to rent hard drive space. It is intrinsically connected with IPFS.
The parent comment is still accurate. IPFS isn't a blockchain and shouldn't be dismissed for this use case, which is more or less what it was designed for.
Filecoin is just for incentives, but IPFS has been running for years without it.
