After all, his Uncle Andrew who did his job poorly and was subject to serious, sleazy, allegations, was accommodated in comfort in an enormous mansion on the Windsor estate? Surely Harry was deserving of at least the same respect?
I wish Andrew would fall into a sink-hole, personally -let's be clear about that!! And some of the RF might also feel like that.
But in the real world, there may be more antagonism to Harry within the family because his choices and actions over the last 5 years are sure to be seen as a very personal treachery (not as in Guy Fawkes, but as in betraying his family). And some members will feel he's had the knives out for them particularly.
Having had experience of family fall-outs I know how deep these feelings go - they're not subject to logic or even fairness, usually. It must seem to W and C and maybe Charles and Camilla, that H has dredged up all kinds of grudges and quarrels which are part of family life, put a nasty spin on them and broadcast them to the world for money and attention. Once out there, they can never be taken back and relationships are changed for ever.
I'm just talking about how family members might feel - not suggesting what might be a fair outcome. I really don't think any kind of comparison between Andrew and Harry are very useful - it's an 'apple and orange' scenario. Both will be sources of shame and embarrassment for but totally different reasons.
