The irony of peddling perceived family slights for a grubby press dollar (the very institution you claim killed your Mother, hated your wife blah blah blah) is not lost on the vast majority of free-thinking people in this county.
Yes, they're feeding the beast and it could really be dangerous for their children. But 'me me me me me me me'. Poor kids.
I do think the staff have NDAs and I think that is quite abusive in itself if they've been bullied. Can they talk about it with private therapists? If not that is really abusive. It would be very interesting to hear their side of the story, but normal people probably don't want the level of press intrusion Harry courts.
Obviously violence is never ok, but there is no real evidence of this. William standing up for staff puts him in quite a good light. Of course, we don't know if this is true either but I can see why Harry would make up lies / exaggerate negative things but don't really know why he'd say something that makes William look like a decent human. But then again, maybe H&M see staff as not fully human lessers so he didn't realise how this would come across.
