Blockchains were never intended for data storage of large files, media, binaries etc. They provide global consensus, which is useful for things like a shared ledger - but it’s expensive.
IPFS (and similar systems like Arweave) are very much like BitTorrent (except nodes seed/pin full files instead of fragments). If no one pins/seeds the file, it won’t be available to others. If you want some data to stay up for sure, you need to pin it - or pay for someone to do it for you. It’s not a magic free storage solution.
