While I share a similar sentiment of disliking Apple's litigious nature as of late, can you really blame the company for attempting to protect its intellectual property?
Yes. It has the choice not to (ab)use the law in this fashion and yet it does. Assuming free will - which is the only sane assumption to keep this conversation focused and tractable - then yes. I can blame them for their own actions.
Especially since Apple's long-standing mottos are think different/we do things differently to the rest of the pack.
