German translation of "Owner" - "Besitzer&quo

In english we call it the "owner" so it would make sense to call it the same thing in german too. If we changed the german term, what would you suggest? And what would it translate to? The problem with changing it is that then it would need to (in theory) be changed for EVERY language. And can you think of a short term that implies the same thing that most people will understand? Owner is far more familiar to the average person than "uploader" or "poster". Even in every day english, "owner" doesn't always imply that you have unconditional ownership of something. You can own a project, but that doesn't mean its physically yours. You could be the "owner" of a leased or financed car, but technically its the banks. Same thing with a house and a morgage, you are called the "owner" but really its the banks.

Not really a whole lot of point in trying to be perfectly politically correct. Now if the term had been "unconditional owner" or "copyright holder" than it might be a good idea to change it. But it isn't, so it probably won't happen. Unless there is another german word for "owner" that doesn't imply "unconditional ownership" (if that is what besitzer means at all).
