Its annoying, as I am against most DRM schemes out there. But to pretend those came from "big tech" is laughable, at best. A ridiculously large portion of "tech" is perfectly fine with sending copies everywhere. Is literally how many of us get our operating system. Music files and shareware copying were huge before the internet. Mod files and other demoscene music sharing was a ton of fun.
Specifically to audible, to complain about their margins without acknowledging that they have built a large part of the market feels dishonest. I remember audio books before audible. Usually ~50 bucks for book. As such, I owned maybe 1. So, congrats, the folks on them could get more of a percent of far far fewer purchases. Getting things for lower cost is exactly why I get more of them. Such that artists have gotten more from me, even with the lower margin to them, from audible than they ever got before. Wanting the same large cut of a smaller sell is entitlement on both ends.
