All innovation explores the limits of performance and behaviour.___
Hacking is just making hardware do something you know it is capable of doing. When the designers don't meet expectations--whether non-tech-related considerations motivate restrictions on permissible usage, or the designers simply fall short in the inspiration department--it is only natural to marshal one's D.I.Y. resources.Superuser should be one of those resources. The contributors here are both helpful and knowledgeable. It's a powerful combination that should be allowed to foster creativity and encourage innovation. Collaboration isn't forced on anyone who isn't comfortable with the ethical foundations of a question--if you don't want to get involved, just don't answer the question.
No country allows its corporations to single-handedly impose statutory limits on its citizens--even when the corporation is as successful and respected as Apple. It is absurd to imagine that any arbitrary EULA might enjoy the force of law.
There is nothing illegal about asking questions that abjure a EULA--you cannot call it a "grey area" if there is no law to skirt.
There is nothing illegal about offering ideas on how one might subvert a EULA. Speculation isn't contravention--and neither one is illegal.
Any site that calls itself Superuser has to allow a degree of freedom for forward-thinking.
