I imagine this is true enough, but then OCR off the computer screen is only for those circumstances where you'd rather avoid dealing with whatever the obscurity is protecting the underlying text/comms security. It's not the only way past the DRM, although it may be the simplest for some situations. Note however that trying to stop people from being able to do such things is why manufacturers like their proprietary devices (kindle and ipad etc.). Plenty of people can install what they want on their PC, it's not so easy on a device locked down by the manufacturer. Such work is, once again, beyond what most people are likely to do just to take copies for their friends and neighbours. As always, serious pirates are a different matter.
