There are damages - Plurk has a right to any money derived from copying their code, including any payments made to the evil outsourcing company and any advertising revenue (gross) that the site brought in during its short life.

That being said, suing MS can only lead to ruin. If they could keep a BS case like SCO on life support for so long, they can certainly keep this running long enough to bankrupt Plurk. I don't know about the legal system in Taiwan though - maybe they could get a judgment against Microsoft before the universe cools.
