I am using the same version as @haywiremk and am seeing the same issue. Furthermore, any data added to S3 for other sources has zeros out the permissions and has root be the owner. It is then impossible to change the permissions to access the data.

@haywiremk - The issue is the version of s3fs that comes in the apt repo. Just compile from source and you will be good.

Could you use the AWS CLI to compare the metadata of an object with the expected and unexpected permissions via:

$ aws s3api head-object --bucket $YOUR_BUCKET --key $YOUR_KEY
{
    "AcceptRanges": "bytes",
    "LastModified": "Sun, 26 Jul 2020 07:21:13 GMT",
    "ContentLength": 0,
    "ETag": "\"d41d8cd98f00b204e9800998ecf8427e\"",
    "ContentType": "application/octet-stream",
    "Metadata": {
        "ctime": "1595748072",
        "mode": "33204",
        "gid": "1000",
        "uid": "1000",
        "mtime": "1595748072"
    },
    "StorageClass": "STANDARD_IA"
}
