While I don't know anything about these cases specifically, or regarding Mandriva's internal structure... I think changing your name to be a rather obvious trademark infringement is a pretty bad place to start (Lindows), and then trying to grab any attention possible to increase market share from there.
In any case I think that legally, sometimes it is appropriate for businesses to come to an end... and not in the, lets separate our assets from our liability so that we can sell off everything, and keep the brand around kind of way, but in that corporations have more rights than living entities in a lot of ways.
I'm very pro business... but despite the spin, I'm unconvinced that anything that has happened in this case is necessarily a bad thing.
