I would expect for a name like KDE they wouldn't have to worry about it. If the FSF doesn't pick up the bill, if the EFF doesn't pick up the bill, if someone else doesn't pick up the bill they'd have a donation drive. There's no way KDE would have to worry about paying lawyer fees if Sony sues them for their own original artwork.
So wait, in order to avoid the risk of trial costs in a situation someone on the internet made up, KDE should ensure that they have to pay trial costs by suing?
KDE would care about trial costs, though. Do they have a budget for that?
