This sucks for the committed Thrashers fans (such as the ones on this board), sounds like a terrible ownership group. On the other side, though, you can see why they would want to sell if the team is just bleeding money, and if nobody local has any interest in buying, that could definitely say bad things about the financial viability of the team.
On a related note, does anyone have an explanation for why Atlanta is such a bad pro-sports market in general? It's a massive city, close to 6 million in terms of metropolitan area. I can get why hockey isn't popular there, but I watch a lot of basketball too and the Hawks get HORRIBLE support too, despite the fact that they've had a young, exciting team that's been one of the best in the east for quite a few years in a row now, and they have a pretty good/successful history too with the Dominique Wilkins teams. It's easy (and likely partly correct) to blame the owners, but is there also maybe some reason why nobody really wants to own a team there, something about the city that makes it a bad pick in terms of support for professional sports teams like the Hawks and Thrashers?
