Theirs other options available depending on your risk appetite. For example, I built a file sharing tool (https://www.fileyeet.io/ https://www.fileyeet.io/) off the back of Storj (https://www.storj.io/ https://www.storj.io/) which is a distributed file storage backed by a crypto coin (maybe one of the few legitimate uses of crypto, although I'm not convinced yet). Storj was a much cheaper option than S3 although I do have to trust that their systems are as secure as the advertise them to be. Likewise, R2 seems like a good "in-between" option. Both R2 and Storj share the S3 API for integrating with them.
