The non technical dependency layers: the Calendar and the Invoice
Five layers, then: format, rendering, fonts, time, price. The first three are technical and largely invisible. The last two are not technical at all, and they are the ones the user feels most directly, in a migration deadline he did not set, in a subscription cost he did not agree to. Listing them together changes the character of the argument. Lock-in is no longer a catalogue of technical grievances of interest mainly to specialists. It is a complete account of dependency, and it reaches every part of how a person works: what his documents are made of, when his tools will stop being supported, and what he will be charged for them.
What unites all five is a single absence: the user has no exit. He cannot take his documents elsewhere without loss because of the technical layers, he cannot escape the vendor’s calendar or its pricing because of the other two. Every one of these dependencies is only possible because there is no door.
That is why I have spent this series on formats, and on rendering, and on fonts, and now on calendars and invoices. They are not separate complaints. They are the same observation seen from different angles, and the observation is this: an open format and a free application are not, in the first instance, about cost or ideology. They are an exit, they are the door that makes every one of these dependencies optional rather than fixed. The Open Document Format and LibreOffice do not promise that you will never depend on anyone. They promise something narrower and more important: the dependency is one you have chosen, and one you can leave.
A vendor’s calendar will always move. A vendor’s prices will always rise. These are not scandals, they are simply what it means to be governed by someone else’s strategy. The only question that matters is whether you are free to walk away when they do. Everything in this series has been an argument that you should arrange your affairs so that you can.
