You did not provide a link so I can’t assess but that blurb is wrong.
Harry does not lose the HRH title. They aren’t working Royals so they don’t use the public title but he is still an HRH.
It’s a technical issue. Harry is STILL a Royal Highness as Prince Charles son. There would have to be a formal process to remove it by a law change.
Think Letter of the law. STILL an HRH but chooses not to use his technical title..or rather the Queen probably forced him to do it.
HRH was stripped in every article I’ve read. The title is given as a member of the senior royals and they have stepped down so the titles of HRH are stripped from them. I haven’t read anything other than that but if you have a link about the legality of an honorary HRH title bestowed by the queen I’d love to read. I admit I’m interesting in all this. ;)

Correct.
I remember that the Queen stripped Diana of her HRH title and it cancelled her security from the Palace. It came out after her death that she may have been safer with it. So I think that is the reason the Queen is leaving them the title for their security people.
