The morality comes from letting the user exercise certain freedoms, which can only be fulfilled with source access.

With the spread of DRM into the everyday world, we can see how this is playing out: coffee machines refusing third-party cartridges, printers requiring users to replace ink even if it's not used up, tractors unable to be repaired by the owner.

A chair is quite close to its source - some people would find it easier to inspect the object than the blueprint. As such, there's no meaningful distinction between a chair and its source. In terms of freedoms though, a nonfree chair would restrict your ability to inspect or alter it. It would turn into dust when altered, or would be covered with a special layer preventing unauthorized repainting or installing a child seat.

All those things refuse the user to enjoy the freedom of operating them whatever way they like, with real consequences. I know I wouldn't buy any of them given the choice, and I consider them malicious. In my book, malice is definitely related to morality.
