Reasoning? All he had to do was leave and act like a grown man and let someone else do the job he couldn't handle. He was never founder for entire time he was in tw-s, then all of a sudden he asked everyone in council if he could be founder, since he was acting as a leader and handling the mass mails since fargo left, we thought that it would be fine to also make him a founder to show recognition for his efforts... like 3 weeks after fighting and making big speeches about becoming a founder, he hits the disband button.
But that aside, it should allow all founders to decide when an entire alliance disbands, not a single douche. It doesn't seem half of the big alliances that have been dissolved were done purposefully by choice of the alliance, but by one founder with his/her panties in a bunch or they are about to quit game, and they think disbanding is the coolest thing to do at departure.
