yep. It serves to justify the subscription though, which is what all businesses want. Ongoing money vs a one-time purchase. I personally quite like the idea of an appliance for email. But adding a permanent subscription that not only costs a lot of money, but will stop working if the company has an outage or goes out of business means it isn't targetted at me. If you require AWS and have offsite backups then the product isn't an 'own your own data' product as it's advertised. At that point, why not just pay for managed email. It's cheaper, and probably easier to migrate if there are problems.
