I'm not going to expound further and risk a message from Weasleboy except to say Roger Waters is more than unsavory.Not sure how you equate listening to albums purchased a long time ago to support, but you do you. Not to mention you can find unsavory things about a great many musicians. John Lennon was self-admittedly abusive towards his first wife, but I'm still going to listen to the Beatles. 🤷♂️
You are right however that there are scumbags everywhere in life. Hell I still listen to old Bill Cosby albums and play World of Warcraft.
