The original Swedish owners of Enemy Unknown AB may be either:
1). Appalled, and devastated to see their baby hit the dust, but reassured they did the right thing by looking at their bank balances.
2) Be gleefully trolling through the sale contract, anticipating that once AU closes they will be free to open a similar site (Avatars Reunited?)
The technology that LL gained by the purchase of AU could more cheaply have been gained by headhunting a few techs from any social networking site, None of it was terribly "cutting edge". I see this as a terrible waste of resources on LLs part. They probably feel the same way, too, but aren't saying.
That being said, I do feel it is better to cut your losses and move on, focusing on your core business.
