Unfortunately, I honestly think the best course of action is to sue Sony for every penny possible.
The case needs to get as much press and possible, and people need to see how completely ridiculous the whole thing is. More and more cases like this need to tie up the court system, wasting everyone's time and money.
A part of me would like to see such a torching strategy. Yet I feel a strong resistance from another part of myself -- a part of me that believes that OSS would do better by taking the high road, by continuing to be one of the few areas/markets/communities, commercial or otherwise, that lives the life it preaches for the world.
If OSS devolves to "one of the pack", then I feel like we'd lose something fundamental and core to the only viable players for the moral high ground strategy. Don't we already have enough companies showing the world how ugly litigation can be?
Oh no, I don't want them to win. At most, SONY will just add a "we use icons from KDE, licensed under LGPL" as a tiny text somewhere. The goal isn't to win a case against SONY and score massive profits from damages. The goal is to not be on the wrong end of a suit.

This is the only way we'll get copyright reform.
