S3 is one-click to provision a bucket, but good luck actually configuring it if it's not really S3. DigitalOcean, Wasabi, Minio, are all different and would need separate instructions in the install guide for how to configure them. The S3 API itself is an insane overly-complex unmaintainable nightmare, only made better by the various libraries that obfuscate how bad it is.

IPFS looks like it's just one REST endpoint with auth. I think you can just apt-install it and grab a token. But I haven't actually gone through it myself yet, so I might be missing something.

IPFS is more resistant to censorship and resilient, in theory, assuming it will actually resolve your file. S3 is reliable with better scaling capabilities.

I'm going to play with ipfs a bit more and see how much it struggles.
