Because ISPs and computer makers don't make a direct profit from the copyright theft, i.e. they don't make any money from advertising carried alongside the transmission of pirated videos.
They do, gibbergibber! For instance, looking at my screen showing pirated videos I'm also able to see the brand of my monitor - Samsung SyncMaster. Go get them too?
