Mine is a free app, that does nothing without a physical device. The DRM system is no login no account, the device is the key. No update costs. Everything calm. The device is even fungible for its purpose. A tool to do a thing and fucks off.

We’re leaving money on the table, for sure, but I really don’t care. I’m going to make something that is biased to the customer, and they’re going to appreciate it.
