- disk space is cheap
- deletes are expensive (time) and slow
- deletes are harder to scale
- can't revert a real delete
- delete's don't fit into an event sourcing architecture
- append only data is better, more durable
I could go on.
Companies that take daily backups. Say a user asked to delete something, do they now go through and comb through their backups (which might even be offsite or in cold storage) and delete it? It's essentially the same thing.
So you're saying that every company that has a backup system, and who don't regularly go through the backups and remove individual files from the backups because users requested it is a lack of respect? So companies that have offsite backups should, according to you, have policies in place where user data is also removed from offsite backups?
