It was unprofessional. I didn’t like the hint that he knows more and will spill it when drunk at a later period. I think whatever happened should have remained private.
This is how Harry has been acting towards his family.
I think it's sad but unsurprising. Businesses in the states are cut-throat. Harry was never prepared for that.
The best thing they can do now is to return to the UK, let Archie and Lili go to a nice private school and serve under William and Kate. Live a quiet and dutiful life. Settle comfortably in a nice stately home, I hope that's what they'll do. It would be the best outcome for them and their kids.
