What?? How can that be a violation of EULA?? Apple got some sort of restriction saying you can't run OSX on a non-Apple product?
Yes.
And what does this discussion have to do with piracy?
Depends how you look at it. EULA violation is normally a civil matter, but installing an OS in violation of the EULA could be construed as making unauthorised copies, which is a criminal offence (Piracy).
