Perfect sentiment. But if they choose to keep their titles obviously the perks out weigh the negatives so while yes confront the lies the rest is probably best managed with the tried and tested don't complain don't explain strategy.
The sense I get is that they aren't complaining about the scrutiny. It IS the lies and the campaign against them.
As for the separation from his family - I'd suggest that this is quite normal in most families where when someone gets together with a new partner with a different frame of reference, there's some disconnect. Family think their way of doing things are completely reasonable and normal but then new partner suggests maybe they're not and the next thing there's war. Long term, in most cases I think, that dies down and everyone gets to some kind of compromise, possibly with some eye rolling and a bit of bitching on the sidelines or maybe that's just me and DH' families'
In this case, the RF have no idea how to react as all of this is outside of their experience. They think negative press is just something that they experience. They don't necessarily have the ability to see the levels to which it's impacting Harry and Meghan. Or if they do, they don't see that they can or should do anything.
As for Harry and Meghan giving up royal status etc I don't think it's as easy as that. Never mind anything else, H IS close to his family so it's a huge step to walk away. Plus, he's been brought up with expectations of duty and responsibility.
