Ultimately I don't blame them for leaving the RF, far from it I respect people for wanting to strike out on their own. The major problem I have with these two is that they desperately cling to their titles.
I know they don't use their HRH's (they've certainly kept them though) but they definitely tried their best to use the term ''Royal'' and they actively use their titles of Dukue & Duchess. It's completely hypocritical and the exact opposite of the mantra they consistently preach to others about progressiveness, women's empowerment, equality and correcting the racist wrongs of historical systems that places some people above others.
It's breathtaking hypocrisy to see them trading on titles that are completely antithetical to what they preach about how society should be in the 21st century. Their titles are a relic of feudalism and are fundamentally anti-democratic and anti-meritocratic. The Cambridges know this, the Queen knows this for goodness sake and it's why they never, ever get political.
Harry himself (not to mention Prince Charles and even worse Andrew) is a poster boy for the absolute stupidity of an institutional monarchy. He is utterly, utterly mediocre. The fact that he, his father and uncles are elevated to high status by accident of birth shows everything that's wrong about this redundant system.
I've spent the majority of my life ignoring the RF but if anything comes of the Sussex soap opera, I hope it's the final eradication of publicly funding this privately immensely wealthy family. Why can't they be like other European royals who are still around but not publicly funded or allowed to have ''pretend'' powers (the royal prorogative powers over parliament). I actually think this will gradually happen during Charles's reign.
