Id wager that they dont put too much money into R&D and just pay one guy to port over the same code from their last last last generation printer to the new one. Over time its become an unrecognizable mess that is just hacked into working and no one ever takes a look under the hood. Their main market is the ink anyways, so making the printer good at what it does is an afterthought

Freedom of speech is from consequences from the government. That means you cannot be prosecuted for insulting politicians for example. But you can certainly be sued in civil court for the same thing.
