I get what you're saying- this is almost certainly a case where one employee was either lazy or ignorant and just found a nice icon. Not a big deal. But, it was in the service of a company and the corporation is responsible for it. In a sane world, what that means is that someone from KDE would point it out to them, and Sony would say "Ooops. That was a mistake. We'll change it. Sorry.". Who knows what happens in the real world.

This a million times over. When I write code, or do a quick Google Image Search for a stupid icon to clean up a UI while I'm at work, I'm doing so in service of the company I work for. If my actions result in me and my company infringing upon someone else's copyrights, it is ultimately my company that is responsible for those actions. My company may retaliate against me (I'm pretty sure there's a "don't fuck up" clause in my work agreement), but my company cannot wash their hands and allow another company or individual to sue me directly for the violation anymore so than I can remove all the code I've written in their products on my last day of employment the same way I pack up the nic-nacs on my desk.
