I don't feel that Alba had "no right" to request that the thread she started be closed. I would never make such a request myself, but that's a reflection of differing attitudes toward "ownership" of a thread. Some folks think of a thread as a boat: If they launch it, they have a right to steer its course. Others, like myself, think of a thread as a message in a bottle: Once you toss it out, you let it go wherever the currents take it. Neither is right nor wrong.
