to me, it is irrelevant where H&M chose to spend xmas and there was no need for them to communicate on it from my perspective. we already knew they would take some months off from the (self created) media drama they got themselves into, so i am sure no one expected them with the royals during xmas anyway.
i am excited to see who shows up this year. W&K have not been to spend xmas with kate's family in a while, i wonder if they will do so next year again, as they only did it once or twice.
It's because the British media and some others make a big issue out of everything this couple does. There was already a lot of speculation going on and they (BP) were probably getting a lot of questions. Better to answer them now and get it out of the way rather than them just not show up during the Christmas walk about the media and rumors going out of control.
I hope the Sussexes have a peaceful and relaxing Thanksgiving/Christmas with Meghan's mom who hasn't been able to share a Christmas with her daughter in 2+ years. I also hope that Doria gets a lot of cuddle time with Archie her only grandchild and his only living grandmother.
I hope the rest of the royal family is able to enjoy their Christmas as well.
