And who says it's a war anyway?
Microsoft and big publishers say it's a war. The goal is TV and Radio broadcast style control of all media. They will sue you in your home (RIAA), at your business (SCO), and at your kid's school (BSA). They don't really care what you do, but they will try their best to have you do as they say.
The goal is to take your money without your consent for any information exchange. You will pay for a M$ license each time you buy a computer. You will pay per minute or byte of conversation on any electronic device, per play of your music, movies novels and textbooks. Your taxes will pay to encoded your information into secret formats and pay again to retrieve it. The new media, paradoxally, will be more expensive and restricted than it's analog and physical predecessors. All of these intentions have been openly declared and loudly demanded by all of the bad actors.
If that's not a declaration of war, I'm not sure what is. The less you know and care, the easier it will be for them to make the world as they wish.
The world does not have to be that way. People do not mind sharing if it cost them nothing and brings greater returns. Excellence thrives in competition and everyone prospers. Success stories are the whole free software movement, which has obliterated the need for non free, and free media: archive.org and creative commons instead of the big three music publishers; YouTube instead of TV; VOIP instead of Telco; Wikipedia instead of expensive paper publications. The economics of electronic data exchange doom the monopoly publishers unless they pass truly unAmerican laws. Fight the bastards by not giving your money to those who would enslave you.
