Maccard = a word for a mac-user person thingie. There's nothing derogative about that.
If people read it as you did though, that might explain the downvotes.
And the attitude I've seen (especially in the OSX 86 community) is that general piracy is completely OK, but you have to buy OS X from Apple, otherwise you are doing something super-duper wrong. Then they move on to pirate Photoshop.
It's a mind-bending sort of ethics, and I was curious about what the reasoning behind it was.
If so, Hackintoshes are, from Apple's point of view, piracy anyway. Apple makes no money on the OS (which they sell for a few dollars) and all their money from the hardware the Hackintosh user is avoiding buying. So whatever ethics are involved are already in a dubious state.
If you mean general Mac users, then, as I and others have said, there isn't a prevalent attitude of condoning piracy (everyone I know who uses Photoshop/Illustrator/InDesign has paid for it).
