The thing is its only the copyrights of individual artists and creators that will die to this.
The big corpos will find a way to protect their value, just you wait.
They will steal from every single creative in the world and then sue them to hell and back if they use anything they them selves “own”
This is not a threat to the copyrights that you want to die.
I mean a pianotuneR (as in a guy that tunes your piano) is pretty expensive.
These apps seem to be marketed as tools for professional piano tuners. And looking just at the screenshots it looks like it has a lot of tools and features outside of just showing the correct pitch.
If tuning pianos is your profession, paying 999$ once and writing it off as a business expense isn’t that far fetched.
(Better be a bloody useful tool though ;) )
