Probably due to optimization of the conversion funnel, it's VERY easy to build things on DigitalOcean without understanding that - unlike many other *-as-a-service - droplets do not include backups and that is your responsibility. As a sysadmin, this is fine since I don't trust a single provider for both prod and backups anyhow, but I fear for those who are just getting started and don't realize this.

I agree that DO handled this situation appropriately, but they should warn people a little more deliberately when they sign up and create a droplet. A checkbox along the lines of "I, user, understand that I'm responsible for backing up my server", with a few links to some how-to articles of the excellent quality that DO is known for, would suffice and empower without reducing the conversion rate.
