This reminds of the tale of Holobass.
They popped up around the start of Myth and got noticed for their holo remixes, with one of the biggest being "Pops on Rocks" with Ame.
Then they got dmca'd on Spotify because Nip Corpo autism.
Which resulted in them seething during that charity stream Ame did where she did karaoke of the above remix.
During said seething; they "joked" about striking the stream, which was for charity, because "muh copyright"
This tanked any and all goodwill the guy had, basically ending their career.
