Right now, the strategy of the media industry appears to be to spend money under the presumption that the amount of money they spend enforcing/lobbying/trying to pass laws to prevent piracy makes economic sense: they will gain/save more money than they spend. This seems unlikely, but probably people have punched the numbers for these companies and concluded that this is the case.

Of course it's the case: their endgame is to get governments to criminalize all copyright infringement and get the taxpayer to pay for all that. Of course, the balance for society as a whole is well in the red, but why should they care?

But the worst is not the economic costs, but the (much more important IMHO) costs in terms of human rights, such as freedom from censorship, privacy, access to a indispensable medium, etc.
