If that's accurate they've had eight years to produce some product/service to establish a strong commercial claim to the name prior to Facebook getting there. They appear to have failed at doing that.

If you're going to stake claim to such a common, short term as your corporate name, it's definitely obvious that you're risking legal conflict with other entities that may claim that name. There's no way they didn't know what they were getting into in trying to use that name (with or without Facebook wanting it).
