I wouldn't say there is no other reason to encrypt sensor data, though in this case, it very well could be proprietary lock-in.
For instance, if enough information is recorded, you could reconstruct the whole flight using the sensor data in a flight simulator. This is very useful in determining exactly when and where a fault took place. There are many cases, however, where you don't want free and open access to that information (think military aircraft flights).
