I think Harry is entrenched in his issues over security , he’s still making a point over it, he’s still at war with the home office. He’s now refusing to visit his father unless he gets security, he’s basically blackmailing him, same as why he won’t bring the kids over. Or Megan. He’s emotionally blackmailing him to get what he wants.
he will stay in a public hotel with just his own security before staying in a royal residence, and then go to Nigeria , of all places, just to make a point and continue his emotional blackmailing of his father, saying basically I won’t see you unless you give me what I want, tax payer funded security.
And he’s stepped it up, telling the world his father didn’t make time to see him when he knew it was a complete and utter lie. His father did make time to see him, even offered him residence, and harry bare faced and proactively lied as he didn’t wish to admit he was refusing to see his father as he wanted security when staying at a palace.
