I'm surprised H has authorised all these statements, given he grew up at the highest level in the RF.
It's pretty well known that H isn't the sharpest tool in the box tbh.
Aside from that he's "all in" regarding this change in lifestyle.
They'd been planning this for a long time before the announcement and had anticipated that having made their demands everyone would agree to prevent a scandal and to "protect" Harry and Archie.
Their mistake was that The Firm has always put the institution of Monarchy before any individual.
Megan probably didn't understand this and Harry didn't consider that this ethos would apply to him.
He thought Granny and Daddy would roll over - without understanding that they couldn't even if they wanted to. Much of what they wanted (security and use of the word Royal particularly) needed not just HMQ's approval but also that of the Government.
Monarchy also needs the support of the people and H&M's actions were generally unpopular. Step away by all means but they woefully misjudged the backlash to their "cake and eat it" approach. The Firm couldn't be seen to condone this. It always had to be "in or out".
So now they're pissed off and being churlish because the grand plan hasn't materialised and give no fucks as too how many bridges they burn now because they think it's not them, it's everyone against them.
Let them crack on....
Let's see in a few years just how much their ex-royal status can sustain their lifestyle.
As E and MrsS found out, a few years down the line and even being a former king had very little allure for the great and good. Just a life stuck with a small group of sycophants in a grace and favour home.
