S3 supports object versioning, which very much will protect you from anything other than writing the wrong data for the entire history of an object.

Versioning is optional and just becomes part of the file data. Write garbage into that and it'll still take a lot to fix it.
Anyway, there's plenty of filesystems that have versioning built in as well.
Besides, I've been tasked with recovering the specific state of a database where every version of every object was available, and it was only some 200k or so records. That took me about 2 weeks. (mostly for writing code that could find a consistent version of the whole thing)
Of course, the dollar amounts dropbox saved are compared to those negotiated prices.
In my experience it isn't so much the storage price itself, but the network transfer that makes AWS absurdly expensive.
Most companies don't need something like S3. They can perfectly suffice with one server, maybe using RAID-1, or just using backups. Data corruption mostly happens through logical errors anyway and nothing in S3 will protect you from that.
