I think the most realistic concern here is amazon scanning your backups. I totally get it. A lot of the reason for retaining total control over the storage medium is that what is being stored isn't strictly legal.
You should locally encrypt 100% of the information you store on someone else's system with strong symmetric encryption. In fact, I think Amazon's legal team would quietly prefer that you do this.

Dumping a bunch of bare files named things like:
into S3 buckets is probably a bad idea.
