People were more sensitive about Lizzie's death because she's probably the only authority figure who's been almost universally liked as a person, mainly because she managed to stay out of all the retarded shit the other royals got into while having a pleasant demeanour and respected moral character. It made a lot of the safe-edgy anti-monarchy jokes come off as desperate performative shit rather than actual humour. I doubt many people will actually care when Charlie kicks it, dude's an adulterer who married his side-piece.
