It has no way to obtain user information, to send back to the vendor, and to track their listening preferences.
I bet you don't even have to register an account to use it; it looks some "local first" thing.
EDIT: I figured it out. The equipment for making records was prohibitively bulky and expensive for individuals to own; no copying was possible. There is always a catch!
Originally I thought it would work more like the RokBlok (https://rokblok.co) and just use a spring or something for power.

BTW, according to Wikipedia, the very first Edison phonographs had electric motors, which were however powered by "hazardous, high-maintenance wet cell batteries" and made the devices very expensive, so they were soon replaced by wind-up spring mechanisms.
Product failed but the name it was given was brilliant and timeless as it's used until today in many languages.
So the company used the wax-cylinder technology for 40 years, and then continued with other technologies until 1979, when they were bought up by Pitney Bowes. Doesn't sound like a failure to me...
