Right now DRM is the death of you being able to preserve the TV shows you love (they'll just disappear from Netflix after some time and you're not allowed to download them even if you paid for them), the death of being able to watch things on planes and the death of being able to watch things if one of your increasingly unreliable ISPs drops a connection.
What if it was legally bound that a securing tech (enforcing users not to abuse content) HAS to be opened in case of future demise of the author company ?
If Apple and iTunes suddenly crash, they have to make a tiny effort into releasing a conversion/stripping tool and/or open source the system so that ex-customers can at least attempt to help themselves.
Netflix is a streaming company. Users have no rights to the content after their contract with the platform expires. Hell, they have no rights to the content if Netflix happens to remove it from the platform.
It's not about businesses failing - content disappears from Netflix and other services all the time. Shows people were watching previous month regularly disappear even though people pay for service. And DRM prevents them from exercising the legal right (in most juristictions, even US) to make private copies and watch them later. Remember VCRs and DVR devices? We changed laws to explicitly allow that.
