I think it's the same with many famous bands
last week I was watching a french docu about Pink Floyd, and Nick mason said in an itw something like :
"when the group decided to separate from Barrett, our manager decided to bet on him, and not on us. So he chose to manage Syd's career, hoping he would become a famous rock star, while we would fall quickly as an obscure psych rock band without future. Of course history has shown that he was wrong, but at that time, everybody "outside the band" would have thought like him, it was objectively the "wisest" option"
