If I'm reading the AWS S3 pricing charts right[0], you get charged 0.09 USD per GB for the first 10 Tb of transfer out of US East.

If 1000 people download my 1 GB file that I host on S3, that'll run me 90 USD.

You can host on Wasabi which is the only object storage I know where out is free, but my understanding is that the storage is more expensive.

By "consumer cloud storage" the GP commenter likely meant to refer to services like Dropbox, Mega, etc.; not to IaaS object storage (which would more appropriately be called "commercial cloud storage.")

Ah that makes sense! I occasionally use Wasabi to sling files around so that's where my mind was when I made the original comment.

I do feel like you do end up paying for storage if you're sharing anything significant in size, which is where torrents become more convenient imho if both parties know how to use a torrent client.
