If I can't throw it in a box for 30+ years then it's not a reliable storage medium.
A server that uses parity drives and regular data checks is a reliable system built on top of unreliable storage. It achieves the same data integrity but it's a lot more annoying and difficult to deal with.
A huge stack of m-discs is not a good option either.
I have a NAS with many terabytes of data stored on ZFS too, but this isn't a solution to the problem because the problem isn't technical one, it's a social one.
We need regulations around this kind of stuff and governments that are willing to break up companies that monopolize industries.
Companies like Autodesk and Adobe for instance have far too much control over very critical markets and the revenue that they extract from them allows them to lock down software in very onerous ways.
No amount of spinning rust and ZFS is going to make running offline versions of Fusion360 or Photoshop easy for the common person.
>>Free software is about having control over the technology we use in our homes, schools and businesses, where computers work for our individual and communal benefit, not for proprietary software companies or governments who might seek to restrict and monitor us
>Fusion360 or Photoshop
Not my Software not my Problem. Ask your country to support alternatives [1] for this kind of software. You're right that critical software is concentrated among a small group of providers. But an even bigger problem is that they're not open source and are sold under US laws (patents, licenses, restrictions etc..).
We have that, it's called spinning Rust with ZFS + Backup (M-DISK?), what's more important where do you buy your stuff for example Nintendo vs GOG.
Don't buy Software that you cant "own".
