It's unclear why the release was canceled. Maybe Sony wants to just put this whole thing behind them. Maybe they want to curtail any further leaks that they feel may be worse. Perhaps the executives feel that being a victim of a foreign nation absolves them of any culpability and they're playing that card to the greatest extent they can. But I highly doubt they're going to make any about face on a policy issue and are still very much against free speech as far as the internet is concerned. If anything this incident will be used to bolster their arguments and to that end maybe it has worked out better for them than "The Interview" ever could.
