Sampling in music is now paid for, it used to be free, as one example.

Sampling is still done, I'm a hobbyist music producer, and friends with many professionals. They have to clear the samples and pay royalties, and they get royalties from sampled tracks.

It's more cumbersome while being fairer, it hasn't stopped at all the practice. As a hobbyist I do it all the time while my professional friends clear their samples before earning money on their tracks.
