At the end of the day we have a 'constitutional monarchy' which basically means the Queen and her family are nothing more than figureheads, they have no real power at all.
Whilst all they are doing is playing a role, then there really isn't a problem, it's when they 'collide' with the real world when things go wrong for them - such as Princess Di not being in that bubble and popping it to escape (James Hewitt, Dodi Fayed and that married doctor for instance) and more recently Prince Andrew and his mate the sex fiend (and that car crash TV interview).
Nobody begrudges Harry and Megan wanting to do the best for themselves and their family but it is how they've attempted to do it that stinks (because they live in that bubble and can't relate to the real world). They don't want to do the 'work' of a royal but won't give up the title - or the money, homes, privileges, lifelong police protection, the private jets, sports cars, exotic months long holidays, etc - indeed they've even tried to 'trade mark' their title, to obviously make a killing of having it linked and logoed to everything - for a hefty price of course!
Apparently Harry feels side-lined from the family but obviously he was always going to be - he is after all the 'spare' and not the 'heir'.
Charles is the next inline and it wouldn't surprise me that he defers it to Willian, whose children are inline after him.
Seems to me the Harry and Megs intend to set up a 'rival court' to make a fortune from the American and foreign markets for themselves - and all sorts of political nightmares that may well set up for us - just imagine if they turned up as the (heavily paid) guests of Iran denouncing America for that recent assassination for instance?
If they want to go and no longer be a royal, then I don't think anyone would have a problem with that (he's inherited millions from his mother and great grandmothers wills) but to seemingly exploit his position for personal gain - whilst being paid from the Civil List and Duchy of Cornwall to the tunes of around £25m per year - and become a political maverick on the world stage is simply taking the biscuit.
As for something TROY said above about the press having no inside information - don't be too sure about that -
The Sun 'broke' the story first (7th January) thus forcing the 'Stepping back' announcement, so clearly they did know what was going on behind the Palace gates!https://www.thesun.co.uk/news/10693487/prince-harry-meghan-move-to-canada/
PS, as for whose idea all this is, do people really think that Harry was the brains behind it all?
