This is basically a masterpiece in missing the point of Tarsnap IMO.

IMO Tarsnap is about being the perfect lifestyle business for an extremely technical engineer, it's something I aspire to build one day also. Billing? Just the most simple model possible. Sales? Nah. Marketing? Nah. Fancy website even? Nah.

Just customers that know what they are buying, are happy to pay for it and software that is exemplary.
