FWIW, I think a couple of things are at play here. It's true that Prince "apparently" got away with much more than the average J-dub. However, if an average male JW sporadically attends meetings because he works out of town, turns in some FS time each month (even if it is "informal"), has no desire to be in the ministry school, pioneer, carry mics or be "used" in any other capacity they can often avoid severe discipline.
The heat gets turned up IF and WHEN they are MS elder etc. who are expected to be EXemplary. It drives Watchtower NUTS if a man has absolutely NO desire to have any of their so called "privileges" (tm).
On the flip side I have close relatives who were in a band who played at weddings, parties, and local restaurants/bars. The CO came to town and gave them an ultimatum: Either quit or loose your MS and Elders positions. They were seriously hurt but the cult in them won and the band no longer played anywhere but at their homes. If they had picked their music they would simply have been treated like the sisters. LOL
