I think you are right about the DRM.
It will prove to be a waste of time. Audio is too easy. Seriously.
Heck, I can make something to just write the stream to a file, and doing that is not hard. Costs less than a CD.
Not so easy if the analog signal only emerges at the earpiece ...
This analog hole is a ridiculously easy hack job with a soldering iron.
"Ridiculously Easy"? - I wouldn't go that far, but very much within the realms of possibility for a determined attacker I'd say.
But down the line .. as actual physical countermeasures become more sophisticated maybe not so.
That's pretty much a policy. If I pay for it, fine. But I have it in generally useful form. No lock-in. Or I don't buy it.
And I don't mind hacking to get it in general useful form. Easy peasy.
To me, a bit of work, perhaps gain a new skill?
Not only easy, but fun, cheap, all that.
What is hard is having to spend or do work just because of a business model. I really dislike all of that. It is visceral.
