For most forms of legal DRM there is alternatives, actually. Not even iTunes
requires users to purchase DRM'd content anymore. The only serious big block
of users of DRM are the movie industry folks and they will come around
The only very troublesome things are going to be things like GSM, which there
isn't any choice in it. Sure its security broken and nobody is allowed to
talk about it or expose it in public, much less fix it, but that is just the
price we pay for having shitastic laws.
