PDF copy protection is either (a) trivially breakable (you just use a PDF
viewer that doesn't honour the 'no-copy' or 'no-print' flags), or else (b)
makes the document too unwieldy to use (because it requires some ghastly
proprietary document viewer that only works on some platforms and plays fast
and loose with your system to prevent things like screen capture).
I don't believe there has ever been *any* ebook format that was both usable
and prevented copying.

(I keep getting bemused by people who actually spend money on PDF software...)
