If we were to die as a company (unlikely), we would reach out to customers well in advance (think >1 year) and ask them to download their data so they could migrate to another provider.

This seems unlikely, however, since our infrastructure costs for the dead man's switch are covered by just a handful of subscriptions. Besides, we host it next to our other more profitable main product, so it gets free maintenance.

We are up for the challenge of making this last for many decades, though. It is a beautiful mission.
