I think there is a wider issue with our interest around celebrity death. When I heard about Eddie Van Halen, I went on Basschat and a notification came up on the 2020 deaths thread, as I had posted before. When I went on it there must have been 20-30 users viewing that thread. I'm not personally a fan of Van Halen but my social media would suggest all my friends were, not that I remember many of them mentioning it.
I guess it us acknowledges a part of our childhoods that has now gone. Personally I have no issue with people posting playing tributes. if I am not interested, I won't click. I thought for years that these public displays started with Diana but Lennon & Elvis show that the public response is generally, um, public.
