It’s too early to judge in my opinion. My guess is that this is part of the estate rationalisation plan and trimming back of finances the king is doing. Andrew can’t afford to keep on Royal Lodge without financial help. I’d wager if he moves to Frogmore Cottage, PoW will have Royal Lodge, and another property will be sold. M&H may well be offered something smaller, after all they are in the UK only very infrequently - maybe they will get use of PoW current small house on the Windsor Estate instead. It’s all about saving money I suspect.
Harry and Meghan will of course be just fine, they can and should look after themselves. But why is Charles doing this? It won’t save anyone any money. It won’t reduce the cost of the monarchy, and numerous other royals have large properties provided for them, including Andrew.
