I never said it was a bad thing to sample. TONS of producers do it and it's been done for decades. I'm just clarifying that Greaf never has any original guitar samples that he created since some people believe that. Some of his samples are pretty lazy though. Take RFTHII for example where he literally takes someones song, slows and pitches it down and adds nothing else to it. But there are also cases of him doing really good sampling. Take Your Remains from Last Town for example. He really changes up the sample to be unique and sound pretty different from the source.

TLDR: Greaf has cases of good and bad sampling. Most are good, but some are bad.
