Maybe to us but just look at what many do because some unqualified "influencer" tells them to through YouTube or Tik-Tok. To many the utterances from these "celebrities" are listened to.
So personally I'd give something raised by Bono relating to an issue that concerns me the same consideration as I'd give the same point raised by somebody on this forum.
For me much depends on the individual, the issue, etc. eg Fergal Sharkey often appears on C4 News discussing the UK Water Companies.He is a celebrity and his frequent appearances on C4 News are probably in part because of his "celebrity" status (from his Undertones days). I never appreciated his music but discussing the Water Companies he is very coherent, raises specific points backed-up be fact, never comes across as a ideological fanatic, etc.
