I would happily buy pre-made decks, but for decks I spend hours crafting myself, I want to know I have access them forever and not lose them if you get bought out or go bust.
Currently you can export the HTML and also as printed sheets. In the next few months we'll enable exporting to formats such as csv/tsv. (This is currently supported in the admin interface, but we haven't made it a user-facing tool yet).
If it's any consolation, we already prepaid the next 2 years for AWS and are cash-flow positive. (i.e. not going bust anytime soon).
Do you have export functionality?
