I think you're moving goal posts here.
Do I trust TMZ if it tells me to do all my life savings into dogecoin? No. Do I believe if it tells me Michael Jackson has passed away? Absolutely.
There is nothing actionable for me with a celebrity's death but I'll take TMZ's word for it until proven otherwise and even then I'd expect tmz to publish a swift retraction.
Whether gen z trust faceless corporations I don't know but as a millennial, I know that it isn't a dichotomy. It isn't like faceless equals untrustworthy and a face equals trustworthy. I'm sure we have all listened to our CEOs and senior leaderships lie / "bend the truth" even when they know we know the truth. The only thing I'd like to urge and caution against is we don't continue the vilifying of future generations like the boomers did to us.
