The problem is, replacing Taylor Swift with its AI counterpart, and to use Taylor's own material to do that without getting her permission or compensating her.
This is not about Taylor even. It's about everyone, you and me, and Taylor and Haggard and Blind Guardian and Sia, etc...
We hated RIAA because they prevented us from listening to the music while trying to get it was hard and expensive. In short, we were not angry because they wanted compensation, but because they have cut the supply without giving us a solution. Now we have iTunes Store and Bandcamp for DRM free music, and nobody is against musicians getting their fair share. As a side note, I used to make music, I know what it entails.
Hacker ethos has ethics. It has do experiment but don't cause harm embedded all over it. It's about experiment and discovery. Not about ripping people off for their own profit (unless you're a black hat of course), and getting things were free was part of sending a message, not monetary gain.
