YouTubers who delete their channel makes me think of an old Hollywood story. Red Skelton to the younger generations he was a successful comedian back in the day he did vaudeville, radio, film, and tv having a show that ran for 20 years 17 of which it was in the top 10 of shows, but was a victim of the great rural purge CBS did in the early 70's. CBS cancelled any show with a tree the joke was to create new shows to appeal to a younger audience on the bright side this did lead to shows like All in the Family and MASH.
But Skelton was heartbroken by the cancellation and owned all the copies of his show and refused to run them in syndication and was rumored to have it his will they were to be destroyed upon his death. Writers of the show sued him because he was going to destroy the show, they worked decades on it was their careers on screen. Skelton revealed his will had no such clause and he went on to say, "Would you burn the only monument you've built in 20 years?".
Skelton was angry but not stupid, he wasn't going to destroy his life's work.
