It's not meaningful to talk about IPFS being expensive, it's like saying bittorrent is expensive. Both are just ways for people to seed a file, and other people to retrieve that file from its hash. There's only as much redundancy as there are people who want to seed it. IPFS is in wide usage because of libgen haha. Currently the resolver can take 30ish seconds, and there's a new, fancier resolver that supposedly takes <5 seconds, which is still pretty high compared to what people are used to but it's a work in progress. There's also IPNS which allows for the controller of a keypair to update the content associated with an identifier. Filecoin is an incentive layer for IPFS that I'm much less bullish on. It's probably what you were thinking of, it's a way to pay money to have someone host or serve something for you on IPFS. It seems pretty underbaked to me but I think it's in the same order of magnitude, cost wise, as AWS.
