|
| Well, isn't that ironic. Sure, the content is "permanently
| available" in a technical sense, but it'll hinge on the permanent
| availability of playback devices deemed suitable by the DRM.

|
| DRM is a scam on the law abiding consumer and the "Blu-ray Disc
| Association" is a cartel.
|
| Honest question: do people still use PCs to watch BD movies?
| Have they ever? AFAIK the rare few people who still have a BD
| movie collections, use dedicated players or their consoles for
| that. Using a PC for that always seemed like masochism from a
| UX perspective so it was never popular.
|
| To play the devil's advocate, I think it was too expensive for
| Intel to invest in patching the SGX IP block vulnerabilities,
| porting it to smaller nodes, and wasting valuable silicone die,
| just so the last 5 remaining people on the planet who still use
| a PC to watch BD movies can now do it from a brand new PC
| instead of using their existing ones.
|
| So, ultimately this problem backtracks to the use of DRM and
| why that's bad, not on Intel who can't financially justify
| supporting such old & niche DRM IP moving forward.

| to be able to see have disappeared from those services.
|
| If you just "want to watch something" but don't care exactly what
| it is, a streaming service is _great_.
|
| However, if you want to watch a _particular_ movie /show
| repeatedly, then you want a Blue-Ray or DVD, _not_ a streaming
| service. No streaming service will guarantee you endless future
| access to a particular video, and that makes them distinctly
| different. Buying and downloading a file would also work in
| theory, but in most cases you can 't legally buy a video file,
| you can only lease video files for a specific device for a finite
| indefinite time. So while that's an option that _should_ exist,
| in practice it usually doesn 't, so disks are the only thing
| _legally_ available for those who want continuous access.
|
| When I want to watch the a particular show, I want to watch
| _that_. Not a random show that may or may not be on a streaming
| service I 'm paying for. The show may not be on _any_ streaming
| service available to me at a particular point in time. Of course,
| I could always go to a pirate site and get access to practically
| everything, but while that 's probably more convenient, I'm
| trying to do things legally.
|
| I think it's fraudulent for vendors to say that you "buy" a video
| when you don't get to keep it permanently, but it does happen.
| What's worse, that fraudulent misuse of the word "buy" confuses
| some people into mistakenly thinking that disks (like Blue-Rays
| and DVDs) can be replaced by streaming services. Yes, they have
| similar purposes, but they are _not_ interchangeable.

|
| Apparently neither do Blue-Rays, since about 10 years from now
| hardware that will read them will become scarce.
|
| In maybe another 5 years it will become an ordeal to get
| _software_ that can bypass the DRM working on a recent system
| with whatever Blue-Ray drive you could scrounge up. This may be
| accelerated by such software becoming even more illegal to
| create and use.
|
| Additionally these kinds of discs physically degrade within
| about fifty years tops. Some can become unreadable after a much
| shorter time. The time range "20-50 years" is often thrown
| around.
|
| If you want to preserve something long term, _the very first
| thing_ you should do is strip any DRM, then save it as a
| "dumb" format on long-term storage. Preferably decentralized
| with multiple backups - use a torrent?
|
| The Blue-Rays sitting on your shelf aren't _much_ better than
| some streaming service.

|
| At least one other person thinks that way and agrees with you,
| and has subsequently filed a lawsuit against Apple for the use
| of the "Buy" button which contradicts the fine print on their
| terms. Check out _Andino v. Apple_
