Honest question: has anyone ever cared for a EULA on hn except for bickering about getting Apple's poorly compatible consumer-os to run on regular consumer hardware?
To be honest, I don't think it is a huge issue for personal use. But when you're running a businesses then it becomes important to pay attention to software licenses. If you intend to get big enough to where you'll be audited for investment or sale, you wouldn't want to have your technology relying on improperly licensed software products.
That being said, I'm among the people who would love to run virtualized OSX.
It is not an EULA for that case. they've taken companies out in silicon valley with other claims. But that was during Jobs times. And I doubt he needed anything legal to go after anybody.
I can't think if a single case.
