Why an odd gripe Doug? The software is a tool just like a camera, so how would you feel if the camera companies said we are no longer allowed to sell are cameras or lenses, once you buy it your stuck with it.
Actually, that's not true..."buying" software is a license of intellectual property not the sale of tangible property. That's a big difference. When you licensed Capture One, to agreed to an end user license agreement–something you should have read when you agreed to it. Yes, it's a click through agreement and I agree most people don't bother to read them (let alone understand them) but you did agree to the license even if you don't know the terms.
Some software companies DO allow a transfer of license–Adobe allows a user to transfer a license after doing the proper paperwork. Phase One apparently doesn't. But if you had read and understood the EULA you would have known.
The fact that a photographers is complaining of a license agreement is, I think what Doug was talking about...and he's right.
