lmao @ your definition of morality.
What scale are you using? Are things black and white in your world? How does nabbing an overpriced studio of software meant to facilitate professional development - and reap the benefits of such a profitable arrangement - reflect on one's character?
Should amateur artists and would-be designers be forced to pay over $1000 for software they intend to use for garage school? Does not nearly every professional endeavor in this country pay what is due to the architect of their virtual studio - if for nothing less than to protect their credibility and adhere to the guidelines of an upright establishment?
Adobe and similar producers are well aware of the countless pirated copies floating about the web. The IRAA, lawyers, shareholders, and our geriatric government are the only greedy parties in this proverbial yin yang. Unless the OP is fishing for a shotgun copy for Pixar's rendering farm, I doubt his interest in a free copy of CS4 is going to effect the media giant in the least...
