They're not preventing anybody from seeing the stuff without paying for it. I doubt there's a new-release movie or popular show that's not widely distributed in HD mere days after it first airs in the theatre or on cable. If people wanted it for free, they could get all of it for free. People don't want it for free. People want to pay for it, or nobody would ever buy a DVD or a movie ticket because you can already get the content for free. We just want it not to be a pain in the ass to use when we buy it, and we'll buy a hell of a lot more. And that means no DRM. Look at what that did for music. Cutting the DRM BS cause online music sales to boom. In January 2008 iTunes dropped DRM - and everybody else who had it soon followed. Global online music sales in 2007: $2.9B. 2011: $6.3B (more than double, in 4 years.)
The media giants are just avoiding selling their product to the people who would prefer to buy it. We're here - with out wallets out - to pay for video that's already ubiquitously available in unrestricted formats for free. All we want is to be able to play it however we want, on whatever we want, to skip the commercials when we're paying cash, to transcode or backup or whatever. Is it so hard to understand that if they quit trying to prevent people from enjoying the content they buy they could be doing a booming business?
And that FBI warning is stupid. Imagine if they put that at the front of every music track.
