I don’t understand the eagerness of most people to go nuclear by adding potentially dangerous arguments when not required.

Use rmdir to remove a directory you expect to be empty, not rm -rf

Audio CDs contain 44.1kHz 16-bit PCM. If you got FLACs out you transcoded them, and transcoding from lossy to lossless is generally undesirable

EDIT: I stand corrected, I forgot that PCM is not a codec.

They don’t want to protect, they want exclusivity.
